Abstract
An optical device may include a non-linear optical medium and an optical coupler coupled to the optical medium. The optical coupler may be configured to multiplex an optical data signal and an optical pump signal onto the optical medium such that an optical idler signal is generated. The power of the optical pump signal may be below a level that results in optical parametric amplification of the optical idler signal. The optical device may further include an amplifier coupled to the optical medium and configured to amplify the optical data signal.
