Abstract

We propose and demonstrate an optical 60 ° hybrid for demodulating optical signals with six-level DPSK modulation format. The proposed device consisting of a paired-interference 2 6 MMI coupler, phase shifters, and 2 2 MMI couplers with an asymmetric splitting ratio of 72 28 exhibited hexagonal phase response over a C-band range.
