Because of the low index contrast of this structure (≈1.2) we had to use a W0.54 defect waveguide to inhibitAuthor/s retain copyrightKeywords: 2-D photonic crystals; Chalcogenide glass; Continuum modes; Crystal nanocavities; Defect waveguides; Light lines; Low index contrast; Optical cavities; Heterojunctions; Phase change memory; Resonators; Photonic crystals Heterostructure cavities; Photonic crystals; ResonatorsHigh-Q (>750,000) photonic crystal nanocavities fabricated from chalcogenide glass fully embedded in an index-matched cladding201210.1117/12.9215262016-02-24
