SOMERSET, England, May 14, 2010 — Fused polarization-maintaining (PM) couplers at 780 nm have been added to the coupler series from Gooch & Housego. Typical applications include power monitoring of PM sources, high-power fiber lasers, fiber amplifiers and fiber gyroscopes.

The 780-nm PM couplers enable accurate monitoring and splitting of optical signals in polarization maintaining fiber. Manufactured using industry-standard all-PM fiber, the couplers are available in any coupling ratio from 1 to 50%. Based on proprietary fused fiber technology, they offer the advantages of very low excess loss and the ability to handle high power.

Standard versions are optimized for launching light into the slow axis to maintain polarization. Optionally, versions for launching into the fast axis can be ordered. There is no additional charge for adding a second input port.

Applications include CATV, lasers, life sciences, medical diagnostics, research, telecommunications, and test and measurement.
