High Sensitivity Receiver Demonstration Using Phase Sensitive Amplifier for Free-Space Optical Communication
Paper in proceeding, 2017
For the first time, phase sensitive amplifier is demonstrated as a pre-amplifier in free-space optical communication. Record sensitivity of 4.5 photons/bit (signal+idler+pump) at 10(-3) BER for 10GBd-QPSK data is achieved, and is 2.5 dB higher than an EDFA pre-amplified receiver.
