1 × N All-Logic Optical Switch Based on Polymer Platform Using Multimode Interferometer

Abstract

Optical Switches

In article number 2400118, Yuexin Yin and co-workers fabricate a 1 × N generalized Mach-Zehnder interferometer (GMZI) based switch on a polymer platform. This scalable structure is realized for 1 × 2, 1 × 3, and 1 × 4 switches. With phase compensations introduced, for the 1 × 4 switch, the bandwidth is 13 times larger for 10 dB crosstalk. Moreover, the all-logic optical switch is demonstrated based on the switch proposed.
