We demonstrate a silicon nanowire based radio frequency spectrum analyser based on cross-phase modulation. We show that the device is accurate, with cross-chirp from photogenerated free-carriers negligible and measure RF spectra for 640Gbaud on-off-keyed data.
We demonstrate error-free wavelength conversion near a = 1550nm at 10Gb/s based on cross-phase modulation in single mode As2Se3 chalcogenide glass fibre. We achieve 1.4dB excess system penalty with 2.1W average peak pump power in 1m of fibre over a 10nm range.
