FO(P)I-10A High Power Fiber-to-Free-Space-Isolators
Polarization Sensitive & Insensitive Versions; Fiber Type SM, PM, LMA, PLMA; 1030 nm to 1090 nm; Isolation ≥30 dB; Power Handling ≤50 W FOP(I)-10A fiber-to-free-space isolators are offered with fiber pigtailed or receptacle-style collimators on the input beam, with typical beam diameters of 0.4 mm to 1.1 mm. With receptacle-style collimators, customers can connect a high-power patchcord terminated with an adjustable FC connector. This option gives the user extra flexibility in the control of beam size propagating through the isolator and allows the user to change the fiber if desired. Isolators are optical devices that allow light to be transmitted in one direction only. They block the source from reflected light, thus preventing any feedback problems, such as frequency instability, relaxation oscillations, amplified stimulated emissions, or optical damage – very critical with the recent dramatic increase in laser output powers, especially in the 1030 to 1090nm wavelength range. To meet this demand OZ Optics has developed a line of high power handling isolators, capable of peak isolation levels of 30 dB to 50 dB for 1030 nm to 1090 nm, depending on the input beam size. OZ Optics uses a patented tilt alignment technique to manufacture isolators with fiber pigtails. Light from an optical fiber is first collimated then transmitted through the isolator. The fibers can be standard single mode fibers or Large Mode Area (LMA) fibers. LMA fibers are used to reduce the optical power density in the fiber core and therefore allow guidance of larger input power levels while still achieving near-gaussian output beam quality. This patented tilt alignment technique allows OZ Optics to offer compact pigtailed devices. The isolators come with built-in windows to prevent dust contamination of internal isolator optics. These protection windows are easily removed and replaced by the user. Custom smaller packages can be made for OEM applications – contact us for more details.

FO(P)I-11/21 Fiber-to-Fiber Isolators
Polarization Sensitive & Insensitive Versions; SM or PM Fiber; 532 nm to 2000 nm; Isolation ≥20 to ≥40 dB; Power Handling 0.5 to 10 W This complete line of pigtailed fiber-to-fiber isolators for wavelengths ranging from 532 nm to 2000 nm combines a free-space Faraday rotator with polarizing optics to provide up to 60 dB of isolation and high power handling with minimum losses. Our isolators are manufactured using OZ Optics' patented tilt alignment technique. Input light from an optical fiber is first collimated, then transmitted through the isolator optics. A focusing lens on the output side of the isolator then couples the light back into the output fiber. This method is highly flexible and allows isolators capable of handling up to 10 W of optical power through single-mode fibers. Isolators are offered in two different versions, polarization sensitive and polarization insensitive. Polarization sensitive isolators are well suited for PM fibers and for some applications where an input free-space beam of constant polarization enters the Faraday optics. However, these isolators are not recommended for SM fibers, as these fibers do not maintain polarization. For this reason we recommend using polarization insensitive isolators with standard SM fibers. Please note however that polarization insensitive isolators are not necessarily available for all wavelengths or power levels.

PMF/QPMF Polarization Maintaining Fibers
350-2200 nm; Core Diameter 2-20 µm; Cladding Diameter 125, 130, 250 µm; Mode Field Diameter 2.3-10.5 µm; Numerical Aperture 0.08-0.2; Polarization Crosstalk <-20, <-25, <-30 dB OZ Optics offers a wide range of optical fibers suitable for many applications. PMF/QPMF polarization maintaining (PM) fibers come in a variety of fiber sizes, operating wavelengths, and fiber types, and can be assembled into patchcords or more complex fiber optic components to suit your needs. OZ Optics categorizes fibers based on fiber type, operating wavelengths, core/cladding size, jacket diameter, and numerical aperture (NA). OZ Optics’ PMF/QPMF polarization maintaining (PM) fibers are a special variety of single mode (SM) fibers, designed to maintain the polarization properties of linearly polarized light sources, provided that the light is launched along either the slow or fast axes of the fiber. The most common method to do this is by adding two stress applying parts (SAP) on either side of the fiber core. OZ Optics’ standard PM fibers use a PANDA fiber geometry, with two circular stress rods. OZ Optics can provide fibers with other geometries, such as Bow-tie PM fibers. Like OZ Optics’ single mode fibers, the wavelength range is limited by their cutoff wavelengths and bend sensitivity at long wavelengths. OZ Optics offers special broadband RGB PM fibers for visible light applications, able to transmit light from 400 nm to 650 nm. Standard PM fibers (PMF) normally have a germanium doped core with a pure silica cladding, while for wavelengths shorter than 600 nm, OZ Optics instead uses fibers with a pure fused silica core with a fluorine doped cladding (QPMF fibers). For many high-power applications transmitting tens of Watts of optical power, standard single mode fibers are not suitable because of their small core size. On the other hand, multi mode fibers suffer from speckle patterns and large beam sizes. Large mode area (LMA) fibers offer a compromise by giving a large core size for high power handling at the expense of a lower numerical aperture, making them more sensitive to bending losses. In many cases, these fibers are not truly single mode, but are better described as low-order multi mode fibers. However, by carefully controlling how light is launched in these fibers and how much they bend, one can transmit nearly single mode light, thus generating output beams that can be focused to the small spot sizes needed for laser marking, welding and machining operations.
