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…
Observation and characterization of mode splitting in microsphere resonators in aquatic environment
Kim Woosung, Sahin Kaya Ozdemir, Jiangang Zhu +1
Whispering gallery mode (WGM) optical resonators utilizing resonance shift (RS) and mode splitting (MS) techniques have emerged as highly sensitive platforms for label-free detecti…
Estimation of Purcell factor from mode-splitting spectra in an optical microcavity
Sahin Kaya Ozdemir, Jiangang Zhu, Lina He +1
We investigate scattering process in an ultra-high-Q optical microcavity coupled to subwavelength scatterers by introducing "splitting quality" Qsp, a dimensionless parameter defin…
