We report an experimental technique for accurate characterization of chromatic dispersion and its slope versus wavelength. The system consists of a fiber-based heterodyne Mach-Zehnder interferometer with a counter-propagating beam which is used to cancel the thermal phase noise. Three different silicon-based waveguides are characterized, obtaining a good agreement with theoretical simulations.
We present the characterization of the nonlinear-dynamics of a CMOS-compatible horizontal-slot waveguide with silicon-nanocrystals, where the temporal behavior of the phase and amplitude of the nonlinear response are simultaneously monitored. These results are complemented with four-wave-mixing measurements.
We report an ultrafast (<40ps) all-optical XOR logic gate based on a silicon nanocrystal-based horizontal slot waveguide. The device consists of a Mach-Zehnder interferometer with three input ports, and is driven by ∼200mW peak power.
