INSTRUMENTS SPECIAL POLARIZATION ACCESSORIES COMPONENTS APPLICATION FAQS GUIDE TIMING/DELAY MANAGEMENT MODULES POLARIZATION MANAGEMENT MODULES - 66- General Photonics Corporation 909.590.5473 http://www.generalphotonics.com Capable of depolarizing lasers with coherence lengths of kilometers, General Photonics’ passive depolarizer is miles ahead of the competition. This patented device comes in a surprisingly small package (85 × 60 × 10 mm) for lasers with coherence lengths less than 10 meters. Devices for coherence lengths in the kilometer range can be custom made. This device is ideal for eliminating 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 rugged package provides high performance and superb environmental stability. Specifications: Center Operating Wavelength1 1310 nm, 1550 nm Operating Wavelength Range ± 50 nm Coherence Length of Light Source 10 m standard, others specify Output Degree of Polarization < 5% Insertion Loss 1.0 dB typical, 1.4 dB max. Residual Extinction Ratio < 0.5 dB Return Loss 55 dB Optical Power Handling 300 mW min.
