Silicon based optical pulse shaping and characterization

Abstract

The high-index contrast between the silicon core and silica cladding enable low cost chip-scale demonstration of all-optical nonlinear functional devices at relatively low pump powers due to strong optical confinement the in silicon waveguides. So far, broad ranges of applications from Raman lasers to wavelength converters have been presented. This presentation will highlight the recent developments on ultrafast pulse shaping and pulse characterization techniques utilizing the strong nonlinear effects in silicon. In particular, pulse compression due to two photon absorption and dual wavelength lasing and ultrafast pulse characterization based on XPM FROG measurement will be highlighted.
