Continuous-wave Cascaded-Harmonic Generation and Multi-Photon Raman Lasing in Lithium Niobate Whispering-Gallery Resonators
Jeremy Moore, Matthew Tomes, Tal Carmon +1
We report experimental demonstration of continuous-wave cascaded-harmonic generation and Raman lasing in a millimeter-scale lithium niobate whispering-gallery resonator pumped at a…
Observation of Spontaneous Brillouin Cooling
Gaurav Bahl, Matthew Tomes, Florian Marquardt +1
While radiation-pressure cooling is well known, the Brillouin scattering of light from sound is considered an acousto-optical amplification-only process. It was suggested that cool…
Brillouin Cooling
Matthew Tomes, Florian Marquardt, Gaurav Bahl +1
We analyze how to exploit Brillouin scattering for the purpose of cooling opto-mechanical devices and present a quantum-mechanical theory for Brillouin cooling. Our analysis shows…
Surface optomechanics: Calculating optically excited acoustical whispering gallery modes in microspheres
John Zehnpfennig, Gaurav Bahl, Matthew Tomes +1
Stimulated Brillouin scattering recently allowed experimental excitation of surface acoustic resonances in micro-devices, enabling vibration at rates in the range of 50 MHz to 12 G…
Stimulated optomechanical excitation of surface acoustic waves in a microdevice
Gaurav Bahl, John Zehnpfennig, Matthew Tomes +1
Stimulated Brillouin interaction between sound and light, known to be the strongest optical nonlinearity common to all amorphous and crystalline dielectrics, has been widely studie…
Precession Optomechanics
Xingyu Zhang, Matthew Tomes, Tal Carmon
We propose a light-structure interaction that utilizes circularly polarized light to deform a slightly bent waveguide. The mechanism allows for flipping the direction of deformatio…
