We experimentally demonstrate an all-optical architecture for the linearization of a phase-modulated interferometrically detected microwave photonic link. We couple off a small part of the phase-modulated signal and combine it with a pump lightwave to produce a comb of idlers in a cascaded four-wave mixing process. The phase-matching requirement of the cascaded process ensures that integer multiples...
We demonstrate a high speed all-optical NAND gate based on four-wave mixing Bragg scattering in highly nonlinear fiber. A 15.2-dB depletion of the signal is obtained and time domain measurements show 10-Gb/s NAND operation.
We utilize a coherent optical comb generator to accomplish source-efficient wavelength multicasting via four-wave mixing in both a highly-nonlinear fiber and a silicon nanowaveguide. We demonstrate 23 multicast channels with error-free operation at 10-Gb/s.
We experimentally demonstrate coherent spectral phase encoded optical code-division multiple access that fully suppresses multiple access interference and speckle noise for the first time without the need for fast nonlinear time gating.
We demonstrate frequency-resolved optical gating using four-wave mixing in a hydrogenated amorphous silicon nanowaveguide. The ultrahigh nonlinearity and the wide conversion bandwidth of this device allow characterization of sub-ps pulses with high sensitivity.
We generate optical frequency combs spanning 75 THz with a 204-GHz spacing using parametric oscillation in an integrated silicon-nitride microring resonator. The comb spacing is uniform to better than 5.2×10−11 relative to the optical frequency.
