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 …

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 …

Droplet encapsulations using liquid or solid shells are of significant interest in microreactors,
drug delivery, crystallization, and cell growth applications. Despite progress in droplet …

The photothermal (PT) signal arises from slight changes of the index of refraction in a
sample due to absorption of a heating light beam. Refractive index changes are measured …

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 study the self-hybridization between Mie modes supported by water droplets with
stretching and bending vibrations in water molecules. Droplets with radii> 2.7 μ m are found …

Optofluidics, nominally the research area where optics and fluidics merge, is a relatively new
research field and it is only in the last decade that there has been a large increase in the …

Optofluidic lasers are an emerging technology for the development of miniaturized light
sources and biological and chemical sensors. However, most optofluidic lasers …

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 …

The solid high quality (Q) factor whispering gallery mode microcavities are demonstrated as
an excellent experimental platform for enhanced light–matter interactions, and are applied in …
