Abstract:
Summary form only given. In recent years, several application schemes based on four wave mixing (FWM) effect in optical parametric loop mirror (PALM), such as wavelength interchange, wavelength conversion and spectral inversion, have been proposed. The generated FWM wave appears to be relatively strong compared to the input signal and control beams used in those scheme, and can be easily separated out from the other beams. In this paper, we demonstrate, the first time to our knowledge, an all-optical demultiplexing of 10 GHz optical input pulses into 2.5 GHz pulses using the PALM.

Abstract:
Apparatus for recovering clock pulses of wavelength division multiplexed optical signals passed therethrough. The apparatus comprises an optically-pumped laser cavity defining a cavity length and comprising a nonlinear medium pumped at a wavelength selected to give efficient parametric amplification within said medium. The cavity length corresponds to an integer multiple of bit periods of at least one of the multiplexed optical signals. The optical signals copropagate through the medium with the pump radiation. The apparatus further comprises an optical path for recirculating a proportion of the output from the laser cavity back through the laser cavity. In this way, idler waves are generated symmetrically about the pump wavelength by four wave mixing with the at least one of the multiplexed optical signals and recirculated through the laser cavity to be amplified by parametric amplification in order to recover wavelength division multiplexed clock pulses.

Abstract:
Apparatus for recovering clock pulses of wavelength division multiplexed optical signals in a return-to-zero format passed therethrough. The apparatus comprises an optically-pumped laser cavity (3, 9) defining a cavity length and comprising a nonlinear medium (3) pumped at a wavelength selected to give efficient parametric amplification within said medium. The cavity length corresponds to an integer multiple of bit periods of at least one of the multiplexed optical signals. The optical signals co-propagate through the medium with the pump radiation. The apparatus further comprises an optical path for recirculating a proportion of the output from the laser cavity back through the laser cavity. In this way, idler waves are generated symmetrically about the pump wavelength by four-wave mixing with the at least one of the multiplexed optical signals and recirculated through the laser cavity to be amplified by parametric amplification in order to recover wavelength division multiplexed clock pulses. An additional amplifier may be provided to compensate cavity losses.
