Inter-polarization 180-degree mixer for reception of M-ASK signals
23 September 2018
We demonstrate a novel receiver design on silicon for local-oscillator(LO)-less detection of single-polarization multi-level amplitude-shift keying(ASK) signals. Reception of 28Gbaud and 56GBaud 4-ASK signals has successfully demonstrated. The receiver uses a novel inter-polarization 180-degree mixer based on adiabatic mode conversion.
