We demonstrate a differential 6-ary PSK-based transmission system with 10-Gb/s NRZ-OOK neighboring channels over 320-km long SMF with in-line dispersion compensation and DSF links and compare its performances with that of a classical PDM-DQPSK-based system.
We demonstrate error-free, no power penalty, all-optical XOR operation for 40 Gbit/s phase-encoded signals in a highly-nonlinear photonic chip. This scheme exploits the Kerr nonlinearity in a dispersion-engineered chalcogenide (As2S3) planar waveguide.
We report optical phase conjugation of wavelength multiplexed signals using a chalcogenide planar waveguide inserted along a transmission link. Distortion compensation of 3 ?? 40 Gb/s RZ-DPSK signals propagating through 225 km of standard single mode fiber is achieved.
We demonstrate broadband wavelength conversion of amplitude and phase-shift keyed signals at 40-160 Gb/s using the optical Kerr-effect in a photonic chip for the first time. This is enabled by a dispersion-shifted, highly nonlinear As2S3 waveguide.
We review the latest advances in dispersion-shifted Chalcogenide waveguides enabling highly nonlinear and low dispersion planar rib circuits of centimetre length. Its performance advantages for more broadband and higher speed nonlinear signal processing are shown.
We review results on the recently developed dispersion-shifted, Chalcogenide waveguides demonstrating nonlinear signal processing on a compact monolithic platform with ultra-broadband capability and moderate launch powers of around 100 mW. Highlight results include broadband wavelength conversion of high-bit rate optical signals, time division multiplexing of 320 Gb/s signals and characterization...
A review of the development and applications of compact highly nonlinear Chalcogenide waveguides for ultra-fast all-optical signal processing is presented. We demonstrate the extreme tapering of a highly nonlinear As2S3 fiber to further increase its nonlinearity by more than an order of magnitude thereby enabling time-division demultiplexing of a 160 Gb/s signal by four-wave mixing (FWM) with significantly...
