Evaluation of Phase Shifted Fiber Bragg Grating and Asymmetric Planar Lightwave Circuit Interferometer to Control Carrier Phase Differences of Optical Time-division Multiplexed Signals

摘要

We have proposed the control method of inter-symbol carrier phase difference of optical time division multiplexing (OTDM) using asymmetric interferometer. In this report, we paid attention to a phase shifted fiber Bragg grating and a asymmetric planer light wave circuit as interferometer and evaluate characteristics of above two key devices and confirm a stability through the OTDM transmission system over 260 minutes.
