Abstract
The polarization dependence of an arrayed-waveguide wavelength multipl exer for a dense WDM system is successfully eliminated by depositing s tress applying film on the waveguide. ne film compensates for waveguid e birefringence induced by thermal stress. 16 wavelength channels with a 0.8 nm spacing are operated with no polarization dependence.
