We demonstrate three-dimensional simulation of a third order silicon-based grating with full-width-half-maximum (FWHM) reflection bandwidth of 4nm. This provides more than 2 orders of magnitude improvement over a conventional side-walled grating structure. The relationship of grating performance over the infra-red wavelength range is also presented.
We demonstrate two- and full three-dimensional simulation of an active silicon-based photonic crystal chromatic dispersion compensator with low power consumption of 114nW and functioning at 40.5MHz. The novel device allows waveguiding and electrical transport to be individually tailored to a large extent.
