Journal ArticleDOI
Parity–time-symmetric whispering-gallery microcavities
Bo Peng,Sahin Kaya Ozdemir,Fuchuan Lei,Fuchuan Lei,Faraz Monifi,Mariagiovanna Gianfreda,Gui-Lu Long,Shanhui Fan,Franco Nori,Carl M. Bender,Lan Yang +10 more
TL;DR: In this paper, it was shown that coupled optical microcavities bear all the hallmarks of parity-time symmetry; that is, the system dynamics are unchanged by both time-reversal and mirror transformations.
Journal ArticleDOI
Exceptional points enhance sensing in an optical microcavity
TL;DR: An alternative sensing scheme is demonstrated, by which the sensitivity of microcavities can be enhanced when operated at non-Hermitian spectral degeneracies known as exceptional points, paves the way for sensors with unprecedented sensitivity.
Journal ArticleDOI
On-chip single nanoparticle detection and sizing by mode splitting in an ultrahigh- Q microresonator
Jiangang Zhu,Sahin Kaya Ozdemir,Yun-Feng Xiao,Yun-Feng Xiao,Lin Li,Lina He,Da-Ren Chen,Lan Yang +7 more
TL;DR: In this article, the authors report real-time detection and sizing of single nanoparticles, down to 30 nm in radius, using mode splitting in a monolithic ultrahigh-quality-factor (Q) whispering-gallery-mode microresonator.
Journal ArticleDOI
Parity-time symmetry and exceptional points in photonics.
TL;DR: The role of PT symmetry and non-Hermitian dynamics for synthesizing and controlling the flow of light in optical structures is highlighted and a roadmap for future studies and potential applications is provided.
Journal ArticleDOI
Loss-induced suppression and revival of lasing.
Bo Peng,Sahin Kaya Ozdemir,Stefan Rotter,Huzeyfe Yilmaz,Matthias Liertzer,Faraz Monifi,Carl M. Bender,Franco Nori,Lan Yang +8 more
TL;DR: Overturning conventional wisdom that loss is bad and should be minimized, Peng et al. show that carefully tweaking the coupling strength between the various components of a coupled optical system can actually result in an enhancement of the optical properties by adding more loss into the system.
