Abstract
A technique is described for fabrication of etched single mode fiber optical waveguide couplers which preserve the polarization state to within 10–4. The coupling ratio is tunable over a broad range (0–90%) during fabrication. Back-coupling is less than 10–3, insertion loss is less than 1.5 dB, and coupling ratio thermal coefficient is about 1% per degree C.
