Loss-induced suppression and revival of lasing
B. Peng, S. K. Ozdemir, S. Rotter +6
Controlling and reversing the effects of loss are major challenges in optical systems. For lasers losses need to be overcome by a sufficient amount of gain to reach the lasing thre…
Interfacing whispering-gallery microresonators and free space light with cavity enhanced Rayleigh scattering
Jiangang Zhu, Sahin Kaya Ozdemir, Huzeyfe Yilmaz +5
Whispering gallery mode resonators (WGMRs) take advantage of strong light confinement and long photon lifetime for applications in sensing, optomechanics, microlasers and quantum o…
Raman-gain induced loss-compensation in whispering-gallery-microresonators and single-nanoparticle detection with whispering-gallery Raman-microlasers
Sahin Kaya Ozdemir, Jiangang Zhu, Xu Yang +6
Recently optical whispering-gallery-mode resonators (WGMRs) have emerged as promising platforms to achieve label-free detection of nanoscale objects and to reach single molecule se…
Statistics of multiple-scatterer induced frequency splitting in whispering gallery microresonators and microlasers
Lina He, Sahin Kaya Ozdemir, Jiangang Zhu +3
We investigate numerically and experimentally the statistics of the changes in the amount of frequency splitting upon the adsorption of particles one-by-one into the mode volume of…
