Gould’s truly fused 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 including single wavelength and wavelength flattened (Broadband/Wideband) (WFC). Our fused PM fiber couplers/splitters offer high extinction ratio with minimum optical loss. Gould utilizes PM fibers such as Panda & bow tie from different suppliers to accommodate your application specific operating wavelengths.
Fused PM couplers usually operate over a certain wavelength band of +/-20nm. Gould’s latest innovative FBT wavelength flattening technology has expanded the operating wavelength band up to +/-50nm, with performance comparable to our Single Mode (SM) Wavelength Flattened Couplers (WFC).
Gould’s Fused Broadband PM Couplers are small in size and exhibit a flat Coupling Ratio response over a broadband of wavelength ranges, suitable for use in Instrumentation, OCT, Test & Measurements, Sensors and Gyroscopes. Splitters are available in a variety of coupling/splitting ratios.
