Silicon photonics wavelength-selective switch with contra-directional couplers
45th European Conference on Optical Communication (ECOC 2019)(2019)
摘要
We propose a novel silicon photonics WSS with sidewall-corrugated contra-directional couplers which does not have an FSR and is suitable for broadband operation. A fabricated 2×2 single-channel WSS demonstrates the expected operation with an outband extinction of 30dB over a wavelength range wider than C-band.
