Abstract

A new integrated optical triplexer based on asymmetric Y-junction with etched branch is proposed and investigated theoretically. The proposed structure uses the ionic exchange technology on a glass substrate with hydrofluoric etching. The proposed triplexer is designed to demultiplex 1310, 1490, and 1550 nm for fiber-to-the-home application with insertion loss less than 1 dB, crosstalk better than 25 dB, high extinction ratio, and wide bandwidth.
