Lasers are the pillars of modern optics and sensing. Microlasers based on whispering-
gallery modes (WGMs) are miniature in size and have excellent lasing characteristics …

We present a comprehensive overview of sensor technology exploiting optical whispering
gallery mode (WGM) resonances. After a short introduction we begin by detailing the …

Optical microcavities that confine light in high-Q resonance promise all of the capabilities
required for a successful next-generation microsystem biodetection technology. Label-free …

Optical microresonators 1, which confine light within a small cavity, are widely exploited for
various applications ranging from the realization of lasers 2 and nonlinear devices 3, 4, 5 to …

Whispering gallery modes (WGMs) have been exploited for a broad range of sensing
applications. However, the vast majority of WGM sensors consist of passive resonators …

The experimental realization of a Kerr frequency comb represented the convergence of
research in materials, physics, and engineering. This symbiotic relationship continues to …

Optical microresonators confine light to a particular microscale trajectory, are exquisitely
sensitive to their microenvironment, and offer convenient readout of their optical properties …

Optical resonators play an ubiquitous role in modern optics. A particular class of optical
resonators is constituted by spherical dielectric structures, where optical rays are total …

Mechanical stress within organoids is a pivotal indicator in disease modeling and
pharmacokinetics, yet current tools lack the ability to rapidly and dynamically screen these …

Microlasers have been widely used in biosensing applications because of their high
sensitivity to changes in local conditions. However, in most applications, the sensitivity limit …
