Optical Splitters/Couplers

We offer an extensive selection of fiber optic couplers/splitters based on three fabrication methods: fusion, micro-optics, and waveguide (PLC). Fusion features the lowest loss (0.3dB) and the highest optical power handling, having wavelength bandwidth typically ±40nm. Miro-optic overcomes fused coupler shortcomings to achieve ultra-broad wavelength bandwidth ±200nm, high polarization extinction ratio >26dB, and good temperature stability. The Micro-optic platform’s flexibility enables further filter and polarizer integration in the package cost-effectively. Planar lightwave circuit (PLC) has the advantages of a large fiber port count in a compact size and broad wavelength bandwidth (±200nm). However, PLC has a higher fiber coupling loss of ~ 1dB and poor optical power handling due to organic epoxy in the light path. We produce premium grade couplers/splitters with hard-to-obtain performance specifications, maintaining an in-house USA production facility. These fiber optical splitters/couplers are available with all types of fiber, including single-mode (SM), multimode (MM), polarization-maintaining fiber (PM), and double-clad fiber (DC) from wavelength 400nm to 2000nm, optical power up to 100W, and operating temperatures up to 300°C. We also produce couplers/splitters with electrically variable ratios.
