Whispering gallery mode biosensors have been widely exploited over the past decade to
study molecular interactions by virtue of their high sensitivity and applicability in real-time …

Whispering gallery mode (WGM) resonators have been exploited as a highly sensitive and
efficient sensing technique in the past few years. They offer the advantages of ultrahigh …

We experimentally demonstrate the high sensitivity of a novel liquid state, whispering-gallery-
mode optical resonator to humidity changes. The optical resonator used consists of a droplet …

Unlike capillary resonance by Rayleigh (Proc. R. Soc. London29, 71 (1879) PRSLAZ0370-
166210.1098/rspl. 1879.0015) and optical resonance by Ashkin (Phys. Rev. Lett. 38, 1351 …

Glass microspheres embedded with Nd3+‐doped nanoperovskites based on yttrium
orthoaluminate are synthesized and used as optical vacuum sensor. Under 532 nm …

Droplets, particularly water droplets, are abundant in both natural and artificial systems.
Their capillary oscillations are governed by surface tension and are therefore distinguished …

It is perhaps surprising that something as fragile as a microscopic droplet could possibly
form a laser. In this article we will review some of the underpinning physics as to how this …

Lasers rely on stimulated electronic transition, a quantum phenomenon in the form of
population inversion. In contrast, phonon masers,, depend on stimulated Raman scattering …

Optofluidic resonators are capable of characterizing various fluidic media. Here, we propose
an optofluidic microbottle resonator (OFMBR) that is applied to generate pendant droplets …

In this work, we study theoretically and experimentally optical modes of photonic molecules—
clusters of optically coupled spherical resonators. Unlike previous studies, we do not use …
