High Power Fiber-to-Fiber 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.

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.
