We compare using nonlinear fiber to a silicon nanophotonic waveguide in implementing a reconfigurable microwave photonic filter. Additional taps are generated via four wave mixing and tap levels are controlled by a programmable filter.
We analyze the effects of pump settings and cavity designs of a mode-locked fiber optical parametric oscillator on the characteristics of the output pulses. Pulse generation at different repetition rates are demonstrated and characterized.
We demonstrate 40 Gb/s all-optical clock recovery using semiconductor fiber laser mode-locked by a nonlinear optical loop mirror. Clock signal with a timing jitter of 372 fs, and a power fluctuation of 0.089 are obtained.
We demonstrate an approach based on a nonlinear optical loop mirror for generating and multicasting UWB signals. Five channels, including 1 monocycle and 4 doublet pulses, are generated from a single Gaussian optical pulse.
