Abstract

Integrated optical wavelength demultiplexers fabricated by K-Na ion exchange on soda-lime glass, based on the two mode interference principle, are described. Channel isolation up to 26 dB is achieved as well as channel spacings between 70 and 220 nm, with guide insertion loss lower than 2 dB. Polarization-sensitive behaviour is observed, which can be exploited to produce polarizers; polarization ratios up to 126:1 have been obtained.
