(a) Sketch of the InP-based planar waveguide; (b) and (c) top and cross-section scanning electron microscopy micrographs of a typical -oriented planar photonic crystal slab .
(a)–(c) Experimental (black lines) and calculated (grey lines) transmission spectra through eight-rows thick -oriented photonic crystal slabs etched through the heterostructures #STD, #OPT1, and #OPT2, respectively. The fitted values for the air filling factor and the loss parameter are reported.
(a) and (b) Experimental (black lines) and calculated (grey lines) transmission spectra through a FP cavity between two four-rows thick -oriented photonic crystal mirrors separated by a spacer (see the inset) and etched through the heterostructures #STD and #OPT1, respectively.
Single mirror transmission , reflectivity , losses , peak transmission , and cavity quality factor values obtained from the spectra shown in Figs. 3(a) and 3(b) for #STD and #OPT1, respectively.
