Recovery of Spectrally Overlapping QPSK Signals Using a Nonlinear Optoelectronic Filter

Abstract

We demonstrate recovery of a weak QPSK signal buried 35-dB beneath an interfering QPSK signal having an overlapping spectrum. This nonlinear optoelectronic filter technique opens new directions to increase spectral efficiency.
