Abstract

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 losses to continuum modes above the light line. By has allowed optical cavities with very high Q (>750,000) to be obtained.
