WebA polarization-independent, high-index contrast grating (HCG) with a single layer of cross stripes allowing simple fabrication is proposed. Since the cross stripes structure can be suspended in air by selectively wet-etching the layer below, all the layers can be grown at once when implemented for vertical-cavity surface-emitting lasers. We optimized the … Web1 de jun. de 2005 · We present a theoretical and experimental study of high-index-contrast waveguides and basic (passive) devices built from them.
