Analysis of phase-sensitive amplification in phase-shifted periodically-poled waveguide for discrimination and amplification of optical vector modulation signal

Abstract

We propose discrimination and amplification device using phase sensitive amplification based on the second order nonlinear optical effects in phase-shifted periodically polled lithium niobate waveguides. The amplification characteristics in phase-shifted periodically polled structures were analysed by using the finite-difference time-domain (FDTD) method.
