Abstract :
We report the fabrication and characterization of both symmetric and asymmetric Mach-Zehnder interferometers (MZIs) with ring resonators (RRs) coupled to both MZI arms using silicon nanocrystals horizontal slot waveguides. Observed transmission dips are due to both MZI destructive interference and resonances of the coupled RRs. Since the slot is filled with a nonlinear material (silicon nanocrystals) the measured structures could be used to implement high-speed all-optical switches entirely fabricated using CMOS processes.
