We report simultaneous I/Q-data monitoring of 100-Gb/s RZ-DQPSK signal using a two-channel time-stretch enhanced recording (TiSER) oscilloscope. TiSER offers a solution to monitoring of high bit rate data.
We propose a compact silicon microring-based analog modulator for generation of 10-GHz sub-octave analog signals, which exhibit high optical modulation-index of up to 46% and carrier-to-noise ratio (CNR) of 57 dB. In fiber transmission, the CNR can be improved further by 10 dB with chromatic dispersion.
