We demonstrate photonic-crystal nanobeam cavities in amorphous SiC. The fundamental mode exhibits intrinsic-Q of 7.69×104 with mode volume of 0.60(λ/n)3. This is, to the best of our knowledge, the highest Q/V value in SiC cavities.
We demonstrate an amorphous silicon carbide (a-SiC) microresonator with optical Q up to 1.3 × 105. This enables us to characterize the third-order nonlinearity of a-SiC with n2 = (5.9 ± 0.7) × 10−15 cm2/W in the telecom band.
We demonstrate a convenient approach for precise dispersion engineering of silicon microdisk resonators via thermal oxidation. This technique potentially enables efficient correlated photon-pair generation for quantum photonics.
We demonstrate silicon carbide optomechanical microresonators with mechanical frequency up to 1.7GHz, mechanical quality above 5500 and optomechanical coupling around 100GHz/nm. The frequency can match the zero-field splitting of the defect spin in silicon carbide.
We demonstrate compact silicon microring resonators suspended in air with ultra-high optical quality, achieving an intrinsic quality factor of 9.2×105 in the telecom band for the resonator with a radius of 9 µm.
We demonstrate electromagnetically induced transparency and slow light in an optomechanical cavity, at cryogenic and ambient conditions, and show effects analogous to electromagnetically induced absorption.
