Abstract
Nonsymmetric three-port integrated optical Mach-Zehnder interferometer configuration is employed to make 0.807/1.3 micrometers , 1.3/1.55 micrometers , and 1.48/1.55 micrometers wavelength multiplexers/demultiplexers. The devices are produced by potassium-silver double-ion exchange process. The effect of thermal post-annealing on spectral behavior of the fabricated devices is investigated. The losses and extinction ratios of the fabricated devices are also determined.
