Modeling the colors of phase noise in optomechanical oscillators

Cijy Mathai, Sunil A. Bhave, Siddharth Tallur

Optomechanical oscillators (OMOs) combine the co-existing high quality factor mechanical and optical resonances in an integrated device to realize low phase noise RF oscillations.…

Comparison of f-Q scaling in wineglass and radial modes in ring resonators

Siddharth Tallur, Sunil A. Bhave

Low phase noise MEMS oscillators necessitate resonators with high f-Q. Resonators achieving high f-Q (mechanical frequency-quality factor product) close to the thermo-elastic dampi…

Electro-mechanically induced GHz rate optical frequency modulation in silicon

Siddharth Tallur, Sunil A. Bhave

We present a monolithic silicon acousto-optic frequency modulator (AOFM) operating at 1.09GHz. Direct spectroscopy of the modulated laser power shows asymmetric sidebands which ind…
