Demonstration of mode splitting in an optical microcavity in aqueous environment
Woosung Kim, Sahin Kaya Ozdemir, Jiangang Zhu +2
Scatterer induced modal coupling and the consequent mode splitting in a whispering gallery mode resonator is demonstrated in aqueous environment. The rate of change in splitting as…
Ultra-sensitive detection of mode splitting in active optical microcavities
Lina He, Sahin Kaya Ozdemir, Jiangang Zhu +1
Scattering induced mode splitting in active microcavities is demonstrated. Below the lasing threshold, quality factor enhancement by optical gain allows resolving, in the wavelengt…
Self-pulsation in fiber-coupled on-chip microcavity lasers
Lina He, Sahin Kaya Ozdemir, Jiangang Zhu +1
We report self-pulsation in an erbium-doped silica toroidal microcavity laser coupled to a tapered fiber and investigate the effects of pump power and taper-cavity coupling conditi…
Scatterer induced mode splitting in poly(dimethylsiloxane) coated microresonators
Lina He, Sahin Kaya Ozdemir, Jiangang Zhu +1
We investigate scatterer induced mode splitting in a composite microtoroidal resonator (Q ~ 10^6) fabricated by coating a silica microtoroid (Q ~ 10^7) with a thin poly(dimethylsil…
Controlled Manipulation of Mode Splitting in an Optical Microcavity by Two Rayleigh Scatterers
Jiangang Zhu, Sahin Kaya Ozdemir, Lina He +1
We report controlled manipulation of mode splitting in an optical microresonator coupled to two nanoprobes. It is demonstrated that, by controlling the positions of the nanoprobes,…
