Gould’s truly fused polarization maintaining (PM) fiber optic couplers, Taps and Optical signal splitters offer high polarization extinction ratio (PER) with polarization launch into a single or dual axis (Slow axis & Fast axis). Gould utilizes our proven Fused Biconical Taper (FBT) process to manufacture high grade polarization maintaining couplers including single wavelength and wavelength flattened (Broadband/Wideband) (WFC). Our PM Components offer high extinction ratio with minimum optical loss. Gould utilizes PM fiber from different suppliers to accommodate your application specific operating wavelengths.
Due to the significant drop of PER at below freezing temperatures, PM couplers usually operate from 0 to +70°C. Gould’s proprietary FBT platform and packaging technology has made it possible to build high performing PM couplers operating reliably from -55°C TO +85°C, without significant changes in PER and other optical parameters over such a wide operating temperature range. These types of PM couplers are very suitable for use in many High reliability systems and modules.
