We demonstrate the all-optical reconfigurable time slot interchange (TSI) of individual bits at 40 Gb/s based on four-wave mixing (FWM) and a programmable planar lightwave circuit (PLC). The PLC is used to generate different control signals (masks) t

We demonstrate RF arbitrary waveform generation based on microwave photonic filtering. We use four-wave mixing in a silicon nanowire to increase the number of taps in an N-tap microwave photonic filter (MPF). Using a programmable optical filter, we c

We propose and demonstrate a novel architecture for four-wave mixing (FWM)-based recognition of spectral amplitude code (SAC) labels in optical packet-switched networks. With a proper code design, a unique FWM idler for each SAC label, referred to as

We report cross-phase-modulation-based wavelength conversion of 10 Gb/s RZ-OOK using a low-stress silicon-rich nitride waveguide. The waveguide is engineered to display flat and low dispersion over the entire C+L bands.

We propose and validate experimentally a time-delay to intensity mapping process based on second-order optical integrators. This mapping provides dynamic control of the intensity modulation profile of a waveform based on a purely passive and linear p

Silicon nitride (SixNy) waveguides constitute a technology platform to realize optical signal processing based on the nonlinear Kerr effect. Varying the stoichiometry of the core (i.e., x and y in silicon nitride) provides an additional degree of fre

Investigation of optical back propagation performances under some practical impairments such as non-ideal optical phase conjugation and non-ideal amplifier noise is presented. The results can also be used to determine the optimum operating system par
