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 … WebIn this article we have demonstrated how a high-index contrast multi-moded waveguide can be used as a partially coherent light source for high-contrast imaging with enhanced …

Web1 de jan. de 2024 · As a consequence, the light confinement from the low-index-contrast periodic cladding is weak and thereby the leaky loss is very high. In contrast, the SCBFs with high-index-contrast claddings are capable of much stronger light confinement in the core by using the photonic bandgap (PBG) effect. Web1 de fev. de 2010 · The high contrast of optical index required for large bandwidth mirror is obtained thanks to the use of a low index AlO x sublayer (n = 1.66) with a thickness T A .
