Paper Abstract

The properties of truly confined modes of a 2D hex horizontal photonic crystal slot slab waveguide are analyzed. Then the dispersion of liner defect waveguide is calculated. In addition, what influence the slots with different height have over the band structure and the group velocity dispersion of the defect mode waveguide are analyzed. Based on these studies, an ultra-compact silicon-based Mach-Zehnder amplitude modulator is proposed. For a design with almost negligible first order chromatic dispersion in an optical bandwidth of 1THz, we predict a modulation bandwidth of 40GHz and a length of about 80µm. This is achieved by infiltrating an electro-optic polymer into a slotted photonic crystal waveguide, the strong field confinement in slotted waveguides and the slow light interaction enhancements provided by the photonic crystal waveguide, where group velocity and dispersion may be controlled.
