Abstract :
Recently, 2-D photonic bandgap (PBG) structures have attracted a great deal of attention due to their simplicity in fabrication and theoretical study as compared to the three dimensional counterparts. Air-guided 2-D slab PBG lasers were successfully demonstrated by the Caltech group (Painter et al. (1999)). However, this air-slab structure is mechanically fragile and thermally unforgiving. Therefore, a new structure that can remove this thermal limitation is required for the 2-D PBG laser to have practical meaning. Here, we present room temperature continuous operation of 2-D photonic bandgap lasers that are thermally and mechanically stable using a thin InGaAsP slab waveguide structure, prepared by wafer fusion and wet oxidation processes
