MEMS-actuated wavelength drop filter based on microsphere whispering gallery modes [PDF]
, 2011 MEMS-enabled tuneable optical coupling between optical microsphere resonators and optical fibre waveguides is reported. We describe the design, fabrication and experimental characterization of a MEMS platform, based on electrothermal actuators, which ...

Photonic lenses with whispering gallery waves at Janus particles
Opto-Electronic Science, 2022 We show that electric field on the plane surface of truncated sphere or cylinders (so called Janus particles) have sharp resonances versus the depth of removed segment of a sphere or cylinder.

Spherical whispering‐gallery‐mode microresonators
Laser & Photonics Reviews, 2010 AbstractWhispering‐gallery modes (WGM) on a spherical surface were first described by Lord Rayleigh at the beginning of the last century, but only after the invention of laser did they start to have some scientific relevance and only during the last two decades there has been a substantial move towards real devices and practical applications.

Nature Communications, 2022 The whispering-gallery mode and the atomic collapse state are two distinct resonances in condensed matter associated with relativistic massless charge carriers. Now, it is shown that these states can coexist in graphene/WSe2 heterostructure quantum dots.

Results in Optics, 2022 Objective: Single-mode operation is very important for laser emissivity; to exceed the emissivity of a single laser, the phase locking of all lasers in an array can be achieved only when the laser array is coupled and operated in single-mode. Methods: In

Wavelength Sensing Based on Whispering Gallery Mode Mapping
Fibers, 2022 We demonstrate a wavelength sensor based on whispering gallery mode (WGM) resonators. For the first time, multiple polymethyl methacrylate (PMMA) microspheres were simultaneously attached to a tapered fiber.
