Detecting single viruses and nanoparticles using whispering gallery microlasers
Lina He, Sahin Kaya Ozdemir, Jiangang Zhu +2
Detection and characterization of individual nano-scale particles, virions, and pathogens are of paramount importance to human health, homeland security, diagnostic and environment…
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…
