Abstract :
The potential of four-level optical phase quantizers towards coherent processing of advanced modulation formats such as 16-QAM is proposed and numerically demonstrated. The work shows that phase quantization can demultiplex 16-QAM into two QPSK signals enabling sub-channel switching and optical regeneration of 16-QAM modulation formats.
