We demonstrate a $32\times 32$ optical switch on a dual-layer Si 3 N 4 -on-SOI platform with low fiber-to-fiber insertion loss (9.61.1..51.dB), low crosstalk (∼35 dB), broad 3-dB bandwidth (∼57 nm) and low power ...

We analyze the equalization enhanced phase noise (EEPN) in carrier-assisted differential detection (CADD) and its dependence on the receiver transfer function. For CADD, by using optical filters instead of a pure optical delay, the EEFN effect could be greatly alleviated when using the transmitter lasers with a large linewidth.

We propose a simple but efficient method to simultaneously characterize the frequency-resolved IQ and polarization imbalance by a single-shot measurement for coherent transceivers based on the simple inter-channel response ratio. We demonstrate the characterization through a successful transmission of a 75-Gbaud PCS-256QAM signal with a 1.05-Tb/s raw data rate.
