We report all-optical wavelength conversion of high-speed differential phase-shift keyed (DPSK) and on-off keyed (OOK) signals using the nonlinear Kerr-effect in an optical chip. This was enabled by four-wave mixing (FWM) of the signal with a continuous-wave (CW) pump laser in a 7-cm-long dispersion-shifted planar rib waveguide in highly nonlinear As2S3 glass. Both conversion of 40-Gb/s DPSK and 160-Gb/s...
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...
The large, ultra-fast Kerr nonlinearity and low nonlinear loss of chalcogenide glasses are attractive for chip based all-optical signal processing. We highlight successes including optical time demultiplexing at 160 Gb/s in As2S3 planar waveguides.
Chalcogenide glasses, which contain S, Se or Te atoms combined with network forming elements such as Ge, As, Sb have the largest third order optical nonlinearity of any inorganic glass. As a result they are attractive candidates for fibre and waveguide devices for all-optical signal processing in the telecommunications bands. In this talk I will review our recent progress in all-optical devices such...
