High-Q (>750,000) photonic crystal nanocavities fabricated from chalcogenide glass fully embedded in an index-matched cladding

Gai, Xin; Luther-Davies, Barry; White, Thomas


We have fabricated a Ge11.5As24Se64.5 2-D photonic crystal containing a hetero-structure cavity fully embedded in a cladding with index of 1.44. Because of the low index contrast of this structure (≈1.2) we had to use a W0.54 defect waveguide to inhibit
