We report on the design and the fabrication of 1D photonic crystal nanobeam cavities with optical resonances around 800 nm, compatible with rubidium, cesium, or argon atomic transitions. The cavities are made of indium gallium phosphide material, a III-V semi-conductor compound which has a large index of refraction (n≃3.3) favoring strong optical confinement and small mode volumes. Nanobeam cavities with inline and side coupling have been designed and fabricated, and quality factors up to 2×104…

Photonic crystal nanobeam cavity strongly coupled to the feeding waveguide

A deterministic design of an ultrahigh Q-factor, wavelength-scale photonic crystal nanobeam cavity is proposed and experimentally demonstrated. Using this approach, cavities with Q>106 and

Deterministic design of wavelength scale, ultra-high Q photonic crystal nanobeam cavities.

This follow-up work provides systematic analysis and verifications of the deterministic design recipe and further extends the discussion to air-mode cavities.

High Q factor InP photonic crystal nanobeam cavities on silicon wire waveguides.

High-quality (Q) factor indium phosphide (InP)-based 1D photonic crystal nanobeam cavities are fabricated on silicon on insulator waveguides and the intrinsic Q factor of these fully encapsulated nanocavities is demonstrated to attain values higher than 100,000.

Fine-tuned high-Q photonic-crystal nanocavity.

A photonic nanocavity with a high Q factor of 100,000 and a modal volume V of 0.71 cubic wavelengths, is demonstrated and a point-defect cavity in a two-dimensional (2D) photonic crystal (PC) slab is improved where the arrangement of six air holes near the cavity edges is fine-tuned.

Ultrahigh-Q photonic crystal nanocavities realized by the local width modulation of a line defect

We propose an ultrahigh quality factor (Q) photonic crystal slab nanocavity created by the local width modulation of a line defect. We show numerically that this nanocavity has an intrinsic Q value

Two-dimensional photonic band-Gap defect mode laser

A laser cavity formed from a single defect in a two-dimensional photonic crystal is demonstrated and pulsed lasing action has been observed at a wavelength of 1.5 micrometers from optically pumped devices with a substrate temperature of 143 kelvin.

Design of Silica Encapsulated High-Q Photonic Crystal Nanobeam Cavity

We report on the design of photonic crystal nanobeam cavity fully encapsulated in silica. The proposed design, based on the principle of gentle confinement of the electromagnetic field, is mostly

High-Q photonic nanocavity in a two-dimensional photonic crystal

A silicon-based two-dimensional photonic-crystal slab is used to fabricate a nanocavity with Q = 45,000 and V = 7.0 × 10-14 cm3; the value of Q/V is 10–100 times larger than in previous studies, underlying the realization that light should be confined gently in order to be confined strongly.

Repeated thermal oxidation and an oxide removal process applied after the removal of the buried oxide layer underneath the nanocavities realized an experimental Q factor greater than eleven million, which is the highest experimental Q ever recorded.

We report on the experimental realization of ultra-high quality factor (Q) designs of the L3-type photonic crystal nanocavity. Based on genetic optimization of the positions of few nearby holes, our
