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.
An all-optical photonic chip RF spectrum monitor with measurement bandwidth >2.5 THz is reported. Using a 16 cm length, highly nonlinear and broadband low dispersive As2S3 planar rib waveguide, 320 Gb/s optical signals are characterized.
Review of recent achievements in chalcogenide glass waveguide and fiber based all- optical signal processing devices utilizing both short and long period gratings as well as the inherent ultra-fast, ultra-strong, third-order nonlinearities.
The first demonstration of all-optical signal processing at telecommunication data rates in chalcogenide glass waveguides is reported. Error-free wavelength conversion via cross-phase modulation in a low-loss, 5 cm-long As2S3 chalcogenide planar waveguide, over a 25 nm wavelength range at 10 Gbit/s, was achieved yielding a Q-factor penalty of 2.3 dB.
