Abstract

A highly dispersive waveguide structure is proposed to efficiently compress and expand ultra short pulses in a package forming a sufficiently small footprint. A sub-wavelength grating is fashioned into a ridge waveguide to take advantage of multiple dispersive effects and spread the mode over a significantly larger area than a standard single-mode waveguide. The structure is designed to take advantage of the amplified dispersion near cutoff. Modal analysis is performed on two variations of the structure using a finite element solver package. The predicted dispersion is sufficient to double the width of a 1 ps pulse within the width of a standard 5 inch ( 127 mm) wafer. A theoretical analysis of the grating component composing the structure confirms that the dispersion values are fully reasonable. (C) 2004 Optical Society of America.
