Effect of thermal post-annealing on spectral transmission of 0.807/1.3 um 1.48/1.55 um and 1.3/1.55 um ion-exchanged Mach-Zehnder interferometer wavelength demultiplexers/multiplexers

摘要

Abstract: Nonsymmetric three-port integrated optical Mach-Zehnder interferometer configuration is employed to make 0.807/1.3 $mu@m, 1.3/1.55 $mu@m, and 1.48/1.55 $mu@m 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. !9
