Gould’s truly fused Pure Silica fiber based polarization maintaining (PM) fiber optic couplers, taps and Optical signal splitters offer high extinction ratio (ER) 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. 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.
These high quality PM Couplers are manufactured mainly using Panda style pure silica fibers which guarantees a high polarization extinction ratio (PER). Operating wavelengths range from 400 to 680nm and Coupling ratio offerings range from 50/50, 20/80, 10/90, 5/95 & 1/99 etc. Other coupling ratio options are available upon request. These components are available in several mechanical packagings. These pure silica core based PM couplers offer excellent resistance to optical loss caused by radiation.
