High Speed Optical Signal Analyses for Microring Resonator Filter Based on FDTD Joined Signal Processing Method

摘要

In this paper, we proposed a FDTD joined signal processing method which was based on superposition theorem and convolution theorem, to analyze the performances of Microring Resonator Filters in time domain and frequency domain. We present the transmission characteristics under high and low transfer rates in different speeds of signal at 10Gbit/s, 40Gbit/s, 80Gbit/s and 100Gbit/s. Transmission characteristics were analyzed in time domain which is agreed well with the result calculated by FDTD directly. Furthermore, the time required by our method reduced significantly compared with FDTD method.
