SPAD Single-Photon InGaAs/InP Avalanche Photodiodes APD

Manual Angled Cleaver; Fiber Type SM, PM; Fiber Diameter 125 µm; Buffer Diameter 250-900 µm; Cleave Angle 8° (±2°); Min. Cleave Length 8 mm Oxford Fiber’s Ox-SAC-08 is the world’s simplest angled cleaver. The single mode (SM) or polarization maintaining (PM) fiber is clamped under rubber rings at two points and bent down onto a sharp diamond blade. The optical fiber is cleaved so that its single mode or polarization maintaining core is at an angle of 8° from perpendicular. This way, the back-reflection from the cleaved end facet is is reduced to <-60dB, avoiding optical noise in telecom systems or eliminating reflections in fiber sensor arrays. If you require a cleaver for any other fiber type or a custom cleaver tailored to your specifications, please get in touch with the AMS Technologies fiber cleaving experts.

This structure provides ultra-high sensitivity at 400 nm to 1000 nm.The C30927 quadrant structure has a common avalanche junction, with separation of the quadrants achieved by segmentation of the light entry p+ surface opposite the junction. With this design, there is no dead space between the elements and therefore no loss of response at boresight.The C30927EH-01, -02 and -03 APD arrays and quadrants are optimized for use at wavelengths of 1060, 900, and 800 nm respectively. Each device type will provide high responsivity and excellent performance when operated within about 50 nm of the specified wavelength.The C30985E is a 25-element silicon avalanche photodiode (Si APD) consisting of a double diffused “reach-through” structure.The standard versions of the Excelitas C30737 silicon APD array series are available with 16 or 64 elements and provide high responsivity between 500 nm and 1000nm.

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.
