HSPC-1000 High-Speed Benchtop Polarization Controller/Scrambler

1310, 1550 nm; IL 1.0 dB; DOP <5%; ER <0.5 dB; RL 55 dB General Photonics’ DEP depolarizer module is a passive device (requiring no external power) that depolarizes laser output. The standard configuration can be used for coherence lengths less than 10 m. Custom units can be specified for coherence lengths of multiple kilometers. The DEP polarizer is ideal for minimizing the polarization sensitivity of fiber optic sensor systems such as systems for quasi-distributed temperature and strain sensing based on fiber Bragg gratings (FBG), systems for distributed temperature and strain sensing based on Brillouin or Raman scattering and systems for distributed acoustic sensing based on Rayleigh scattering. It can also help to eliminate the effects of PDL or polarization sensitivity of optical components and instruments. Equally important, it can be used for depolarizing pump lasers to eliminate the polarization sensitivity of Raman amplifiers. The DEP polarizer is packaged in a small (85 × 60 × 10 mm), rugged aluminium box, providing high performance and superb environmental stability. The internal structure and package size may be different depending on the coherence length or spectral width of the light signal to be depolarized.

PMD 0.5 ps; Optical Power Handling 500 mW OZ Optics' EOPC high-speed electro-optic polarization controller is based on a novel, low-loss, high-speed, free-space electro-optic crystal technology. It provides a simple, efficient means to quickly manipulate the state of polarization by applying an external voltage. High-speed polarization state management is enabled using two to four crystals in a row with remarkably low loss, all housed in a compact and robust butterfly package. The device can be offered with 2, 3 or 4 crystals (depending on the customer’s requirement), and by applying external voltages one can change/manipulate/control the output polarization state. For endless polarization control, a device with 4 crystal elements is required, while a 3-elements device will be sufficient for polarization scrambling mode operation. The compact, motionless, and vibration-free design allows fast linear response with less than 10 μs response time to the control signal. The controller's rapid response speed easily handles changes in polarization, caused by the external environment, and is highly suitable for polarization controlling and scrambling to either average PDL and PDG effects, or for making PMD, PDL or DOP measurements. This makes the EOPC device ideal for precise test and measurement applications.

3 Stage Scramblers or 4 Stage Controllers Available; 1250 to 1650 nm (Others on Request); Insertion Loss <0.4 dB; Polarization Dependent Loss <0.06 dB; Fiber Type SM OZ Optics' EPC series of electrically driven polarization controllers provides a simple, efficient means to manipulate the state of polarization within a single mode (SM) fiber. Employing a novel mechanical fiber squeezing technique, the device is controlled by either three or four (depending on the model) input voltages that the user can vary over a ±5 V range to provide endless polarization control in a robust, easy to operate package. The EPC controllers’ rapid response speed easily handles changes in polarization caused by the external environment and is highly suitable for polarization scrambling for either averaging PDL effects or for making PMD or PDL measurements. Because the fiber within the device is continuous, all insertion losses, return losses, and PDL effects are limited only by the fiber itself. This makes it ideal for precise test and measurement applications. EPC polarization controllers are available in either a three or four channel configuration. The EPC-300 three-channel system is ideal for polarization scrambling applications such as for polarization averaging or PDL measurements. The added redundancy of the EPC-400 four-channel version opens the way to continuous polarization control, without having to occasionally reset the device when a controller reaches its limit. The unique design of the OZ Optics EPC series of polarization controllers means that they do not require any dedicated driver circuitry. There are no internal voltage multipliers or high voltage signals to worry about. Thus operation is safe and simple.

Center Wavelength 400 to 2050 nm; Insertion Loss Typ. 0.5 to 1.0 dB; Return Loss ≥40 to ≥70 dB; Polarization Extinction Ratio 20, 30; Fiber Type SM, MM, PM OZ Optics’ FOP series of fiber optic polarizers are designed to polarize the output from a light source or fiber and launch it into an output fiber. These polarizers typically consist of input and output collimators with a plate polarizer in between. Broadband polarizers are used, so the power extinction ratio is maintained for up to several hundreds of nanometers. The same polarizer, for example, may be used for 1300 nm to 1600 nm. The power extinction ratio is the ratio between maximum and minimum output power as the input polarization state is changed. This is different from the output polarization extinction ratio, which is a measure of the ratio between the power in the two axes of polarization maintaining fiber – this value is only applicable when the output fiber is polarization maintaining (PM) fiber. The power extinction ratio will always equal or exceed the polarization extinction ratio. OZ Optics offers fiber optic polarizers in four sizes. The original 12.5 mm diameter size is best suited for non-telecom wavelengths and for custom designs. The larger size is also well suited for high power applications. Polarizers capable of transmitting several Watts of power have been made with this technique. The 5.5 mm diameter size is well suited for telecom wavelengths, such as 1310 and/or 1550 nm, while the 4 mm diameter option is best suited for low-cost systems where lower output extinction ratios are acceptable. Finally, OZ Optics offers a version that is only 3 mm in diameter, featuring exceptionally low return losses and superior performance over a very broad temperature range. Key Features: Rugged and Compact Housing Single Mode (SM), Multi Mode (MM), Polarization Maintaining (PM) and Fiber Combinations Available Miniature Sizes Available Wide Range of Available Wavelengths: 400 to 2050 nm High Extinction Ratio up to 40 dB Low Loss Low Back Reflection Applications: Fiber Amplifiers; System Polarization Extinction Ratio Conditioning; Measuring Polarization Extinction Ratio; Sensors; Integrated Optics; Interferometric Sensors; OCT Systems

Center Wavelength 633-1550 nm; Typ. Insertion Loss 0.5-0.8 dB; Return Loss 40, 60 dB; Polarization Extinction Ratio 20-30 dB; Fiber Type SM, MM, PM; Rotation Angle @Center Wavelength 45° OZ Optics’ FOR/FOFM pigtail-style Faraday rotators change the polarization state of light traveling through them. The output polarization state is rotated by 45 degrees with respect to the input polarization. When combined with a mirror, the reflected light is rotated by another 45 degrees, resulting in a 90 degree rotation. In addition, the polarization handedness is reversed by the mirror. This results in a reflected polarization that is orthogonal to the original polarization. This is useful when used in interferometers, because polarization changes through the fiber are cancelled out on the return journey. Different Faraday rotator materials are applicable to different wavelengths. At 1300 nm to 1600 nm, small powerful rotators allow for very compact packages. From 633 nm to 1064 nm, less powerful rotators materials requiring much longer lengths and larger magnets are used. This accounts for the wide range of package sizes for different wavelength regions. Rotation accuracy is very tightly controlled at 1300 nm to 1625 nm (standard ±3 degrees single pass — with ±1 degree available) but less controllable at lower wavelengths (±3 degrees standard). Faraday rotator mirrors are readily available at telecom wavelengths (1300 nm to 1550 nm). For shorter wavelength applications where an Faraday mirror is required, it can be constructed using a Faraday rotator with a polarization maintaining fiber output pigtail and a polarization maintaining fiber pigtailed fixed reflector. Key Features: Single Mode (SM), Multi Mode (MM), and Polarization Maintaining (PM) Versions Available Wide Range of Center Wavelengths: 633 nm to 1550 nm Low Insertion Loss: 0.5 dB to 0.8 dB Typ., 0.75 dB to 1.0 dB Max.

400 to 2200 nm; Return Loss ≥40 to ≥60 dB; Available Polarization Extinction Ratio >35; Fiber Type SM, Coating ≤400 µm OZ Optics’ FPC/HFPC/PFPC series of fiber polarization controllers allows to convert any input polarization to any desired output polarization. These devices combine the compact size and ease of use of standard bulk optics systems with low cost, low loss and low back reflection. FPC/HFPC/PFPC controllers work by applying pressure with an adjustable clamp. The pressure on the fiber causes a birefringence within the fiber core, causing the fiber to act as a fractional wave plate. Varying the pressure varies the delay between the fast and slow polarization components. The clamp is rotatable, allowing to change the direction in which the stress is applied. This allows any output polarization to be achieved. The process is simple and quick, output polarizations exceeding 30 dB can be routinely achieved in seconds. FPC/HFPC/PFPC fiber polarization controllers work with single mode (SM) fiber of any wavelength. For multi mode (MM) and polarization maintaining (PM) fiber, AMS Technologies offers OZ Optics’ FPR series of polarization rotators, controllers and analyzers. FPC/HFPC/PFPC fiber polarization controllers are offered in three versions. The FPC in-line polarization controllers can be inserted into a customer’s own single mode fiber. OZ Optics now provides this unit in a miniature size housing for applications where space is critical. FPC controllers can be used with any wavelength single mode fiber and is designed to work with 250 and 400 µm jacketed fibers. With the PFPC devices, pigtailed versions are also offered. PFPC versions are available with any size of cable or fiber and with your choice of connectors. Finally, HFPC connector receptacle style controllers are available, using a short section of fiber terminated with female receptacles.

Input Power 200 mW OZ Optics’ FPR line of polarization rotators, controllers and analyzers manipulate and control the state of polarization of an input beam of light and couple the adjusted light into an output fiber or detector. These systems typically consist of an input with fiber pigtail or connector receptacle, from one to three polarization optic components and an output coupler with fiber pigtail or connector receptacle. The FPR product line uses bulk waveplates and polarizing glass to accomplish the polarization control. Each polarization optic stage can be removed without loss of coupling. These stages may be replaced or interchanged as the application requires. Separate stages with polarization optics mounted in a rotary platform may be purchased to allow using only one fiber optic assembly for multiple applications. Three types of polarization optics are employed: Plate polarizers, with high extinction ratio and low loss, half wave plates rotating the plane of polarization and quarter wave plates changing the ellipticity of the input light. Consult AMS Technologies for special component performance requirements. For extreme applications, custom achromatic waveplates can be supplied that allow operation over wider bands. These components are much more expensive than simple waveplates and detailed requirements should be supplied to ensure the proper component is supplied. OZ Optics manufactures two standard sizes of FPR devices. The standard size uses 2.5" square rotational stages and is the preferred choice for applications where frequent adjustments must be made or repeatability is important. The miniature stage uses 1" stages to fit into tight spaces and is preferred for use in equipment boxes or where a single state needs to be found and subsequent alignment is minimal.
