Magnetic-Free Silicon Nitride Integrated Optical Isolator
Hao Tian, Junqiu Liu, Anat Siddharth +5
Integrated photonics has enabled signal synthesis, modulation and conversion using photonic integrated circuits (PIC). Many materials have been developed, among which silicon nitri…
Ultralow-noise frequency-agile photonic integrated lasers
Grigory Lihachev, Johann Riemensberger, Wenle Weng +8
Low-noise lasers are of central importance in a wide variety of applications, including high spectral-efficiency coherent communication protocols, distributed fibre sensing, and lo…
Observation of stimulated Brillouin scattering in silicon nitride integrated waveguides
Flavien Gyger, Junqiu Liu, Fan Yang +6
Silicon nitride (Si3N4) has emerged as a promising material for integrated nonlinear photonics and has been used for broadband soliton microcombs and low-pulse-energy supercontinuu…
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…
