Quantum-dot microlasers based on whispering gallery mode resonators. [PDF]
The use of epitaxial In (Ga)As quantum dots and relatively simple post growth methods make it possible to realize microdisk lasers capable of operating without temperature stabilization at elevated temperatures.

Spatial Multiplexing of Whispering Gallery Mode Sensors
Whispering gallery mode resonators have proven to be robust and sensitive platforms for the trace detection of chemical and/or biological analytes. Conventional approaches using serially addressed resonators face challenges in simultaneous multi-channel (i.e., multi-species) detection.

Reconfigurable Liquid Whispering Gallery Mode Microlasers [PDF]
AbstractEngineering photonic devices from liquid has been emerging as a fascinating research avenue. Reconfigurably tuning liquid optical micro-devices are highly desirable but remain extremely challenging because of the fluidic nature. In this article we demonstrate an all-liquid tunable whispering gallery mode microlaser floating on a liquid surface ...

A scatterer-assisted whispering-gallery-mode microprobe
Abstract A fiber-based whispering-gallery-mode (WGM) microprobe, combining both the high optical field enhancement of the WGMs and the compact structure of the optical fiber, is highly desired for sensing and imaging. Here we report a WGM microsphere resonator coupled to a single-mode fiber interfaced by a graded-index lens.

Whispering gallery mode hybridization in photonic molecules [PDF]
This work takes inspiration from chemistry where the spectral characteristics of the molecules are determined by hybridization of electronic states evolving from the individual atomic orbitals. Based on analogy between quantum mechanics and the classical

Single whispering-gallery mode lasing in polymer bottle microresonators via spatial pump engineering [PDF]
Single-mode lasing in whispering-gallery mode (WGM) microresonators is challenging to achieve. In bottle microresonators, the highly non-degenerated WGMs are spatially well-separated along the long-axis direction and provide mode-selection capability. In

Efficient coupling of free propagating light into Whispering Gallery Modes [PDF]
Whispering Gallery Mode resonators are dielectric structures with cylindrical symmetry. They are typically excited with an evanescent field leaking out of a tapered fiber or a waveguide.
