We design a photonic crystal hetero-slab-edge microcavity sustaining surface mode with high quality factor ~5.4 times 105 and index sensitivity of 591 nm/refractive index unit by mode-gap effect. Lasing actions from real devices are also observed.
We fabricate 12-fold quasi-photonic crystal microcavity with size-controlled post for electrically-driven structure by fine-tuning wet-etching time. Improved thermal properties of microcavities with different post sizes are investigated both in finite-element method simulations and experiments.
In this report, we investigate the fabrication process of 12-fold quasi-photonic crystal microcavity with size-controlled nano-post beneath for electrically-driven structure by fine-tuning the wet-etching time. By finite-element method, we simulate and analyze the heat transfer behaviors of microcavities with different nano-post sizes and shapes. From the real devices, we obtain whispering-gallery...
