Abstract
We design an ultra-compact low power all-optical modulator by applying dispersion engineered slow-light waveguuide in photonic crystal Mach-Zehnder interferometer (PhC-MZI) arms, which are infiltrated by optofluidic having high nonlinearities. Nearly zero dispersion regime brings us a 22-μm long PhC-MZI to operate as a modulator with an input power as low as 3 mW/μm. By attaching a coupling section about 3.36 μm long and inserting the light through a directional coupler with the lenght of 2.1 μm, losing power from the input port has been decreased.
