Abstract
Enhanced mode selection is facilitated by incorporating compact two dimensional photonic crystal gratings into Fabry-Perot lasers. The gratings are etched directly through the active layer and interact strongly with the guided mode. A high mode-selectivity 2D grating which is significantly wider than the ridge waveguide structure is investigated. The mode selectivity for the structure is -37 dB. The enhanced selectivity afforded by the broad 2D grating is attributable to a novel and robust photonic bandgap mechanism: transverse mode beating.
