Integrated high quality factor lithium niobate microdisk resonators.
Lithium Niobate (LN) is an important nonlinear optical material. Here we demonstrate LN microdisk resonators that feature optical quality factor ~10(5), realized using robust and scalable fabrication techniques, that operate over a wide wavelength range spanning visible and near infrared. Using our resonators, and leveraging LN's large second order optical nonlinearity, we demonstrate on-chip s...
متن کاملHigh-Q lithium niobate microdisk resonators on a chip for efficient electro-optic modulation.
Lithium niobate (LN) microdisk resonators on a LN-silica-LN chip were fabricated using only conventional semiconductor fabrication processes. The quality factor of the LN resonator with a 39.6-μm radius and a 0.5-μm thickness is up to 1.19 × 10(6), which doubles the record of the quality factor 4.84 × 10(5) of LN resonators produced by microfabrication methods allowing batch production. Electro...
متن کاملHIGH kt×Q, MULTI-FREQUENCY LITHIUM NIOBATE RESONATORS
This paper presents design and vacuum measurements of lithium niobate (LN) contour-mode resonators (CMR). By carefully positioning the inter-digital transducer (IDT), we achieved CMRs with kt×Q of 7%*2150=148 (IDT @ node) or resonators with very high kt of 12.3% and spur-attenuated response (IDT @ anti-node). In addition, we demonstrated resonators with frequencies ranging from 400MHz to 800MHz...

متن کاملChip-scale cavity optomechanics in lithium niobate
We develop a chip-scale cavity optomechanical system in single-crystal lithium niobate that exhibits high optical quality factors and a large frequency-quality product as high as 3.6 × 1012 Hz at room temperature and atmosphere. The excellent optical and mechanical properties together with the strong optomechanical coupling allow us to efficiently excite the coherent regenerative optomechanical...
