A Novel Asymmetric Interleaver
不等带宽光学梳状滤波器

The design principle of asymmetric interleaver with 50 GHz spacer is analysed. A novel structure based on Mach-Zehnder interferometer was proposed. With theoretical analysis and simulation, the choosing of parameters is suggested. The nonlinear phase feature of the reflective beam from Gires-Tournois resonator is used to abate the ripple and increase the flat-top passband.
