Abstract :
We analyzed S/N-ratio characteristic by coherent crosstalk of 2times2 and 4times4-cascaded Mach-Zehnder interferometer-type photonic switches. The S/N ratios by the coherent crosstalks are as high as 25[dB] and 28[dB] for 2times2 and 4times4-cascaded switches, respectively, under the optimal MMI width conditions.
