In this article, an integrated-optic polarization-insensitive wavelength multiplexer that is based on an arrayed-waveguide grating was described, and the multiplexing operation of 16 wavelength channels with a 0.8 nm spacing was confirmed to be independent of the polarization state.Abstract:
An integrated-optic polarization-insensitive wavelength multiplexer that is based on an arrayed-waveguide grating is described. Polarization dependence due to thermal stress was eliminated by depositing an a-Si birefringence compensation film on the arrayed-waveguide. The multiplexing operation of 16 wavelength channels with a 0.8 nm spacing was confirmed to be independent of the polarization state. >read more
