摘要：

We propose and demonstrate an optical 60 degrees 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.
