Carrierless coherent receivers based on phase retrieval (Conference Presentation)
Author(s): Yuki Yoshida

Paper Abstract

Toward an ultra-compact optical coherent transceiver solution, recently, carrier-less full-field detection techniques based on phase-retrieval (PR) have been proposed. In these PR-based receivers, optical phase information is recovered digitally from multiple intensity-only measurements by using the PR algorithms, such as the Gerchberg-Saxton algorithm and the Wirtinger flow algorithm. Any local lights or reference lights such as in the Kramers-Kronig coherent receiver are not needed. In this talk, the recent advances in the PR receiver are introduced including the experimental demonstration of PR-based carrier-less coherent detection of polarization-multiplexed QPSK signals only by using a 2-D photodetector array.
