Experimental Demonstration of Reconfigurable “Digital Average” of Two 20-Gbaud Phase-Encoded Data Channels Using Nonlinear Optical Wave Mixing

Abstract

We experimentally demonstrate the reconfigurable “digital average” of two 10/20-Gbaud phase-encoded data channels using two nonlinear optical stages. In the first nonlinear stage, we compute the average. In the second nonlinear stage, we multicast the average result to the input signals wavelengths.
