Abstract
We experimentally demonstrate a novel receiver architecture based on injection locking for demodulating DPSK/ASK modulated signal with ASK extinction ratio exceeding 8 dB. The receiver exploits the limiting amplification of injection locking and enhances the performance of the DPSK stream.
