Breakthrough switching speed with an all-optical chalcogenide glass chip: 640 Gbit/s demultiplexing
We report the first demonstration of error-free 640 Gbit/s
demultiplexing using the Kerr non-linearity of an only 5 cm long
chalcogenide glass waveguide chip. Our approach exploits four-wave
mixing by the instantaneous nonlinear response of chalcogenide. Excellent
performance is achieved with only 2 dB average power penalty and no
indication of error-floor. Characterisation of the FWM efficiency for the
chalcogenide waveguide is given and confirms the good performance of the
device
