Paper Abstract

We propose the integration, in a single glass substrate, of a 0.807/1.3 micrometers wavelength multiplexer, a 1.48/1.55 micrometers wavelength multiplexer, and a 1.30/1.55 micrometers wavelength multiplexer followed by a 1/8 splitter by potassium and silver double-ion exchange. The wavelength multiplexers are based on nonsymmetric three-port Mach-Zehnder interferometers, and symmetrical Y-junctions are used for achromatic splitting. The facet-to-facet excess loss in the 0.807/1.3 micrometers and 1.48/1.55 micrometers multiplexers is less than 3 dB and in the integrated 1.30/1.55 micrometers multiplexer and 1/8 splitter less than 2.65 dB. The device can be used, in connection with an Er-doped fiber, in future wavelength division multiplexing subscriber networks, in which amplification is needed at 1.3 micrometers and 1.55 micrometers wavelength regions.
