Exceptional Antimodes in Multi‐Drive Cavity Magnonics

open access: yesAdvanced Electronic Materials, EarlyView.
Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.

Effect of tapering diameters with microbottle resonator for formaldehyde (CH2O) liquid sensing

open access: yesSensing and Bio-Sensing Research, 2019
In this study, we demonstrate the effect of the microbottle resonator (MBR) based on whispering gallery modes (WGMs) with two different diameters of tapered microfibre and its experiment with the formaldehyde (CH2O) liquid sensor. The MBR with the bottle

Whispering gallery mode

open access: yesEos, Transactions American Geophysical Union, 1973
High altitude balloon platforms positioned a thousand miles apart have been used successfully in an experiment to establish the feasibility of a technique for propagating medium length radio waves through the D layer, the lower layer of the ionosphere.The new technique is called the D‐Layer Whispering Gallery Mode because of its similarity to the ...

Nonlinear properties of high-Q optical microresonators in normal dispersion range

open access: yesEPJ Web of Conferences, 2017
We demonstrate the generation of Kerr frequency combs and platicons in whispering gallery mode crystalline microresonators in normal group velocity regime at 780 nm and 1064 nm wavelengths.

Controlling the Frequency-Temperature Sensitivity of a Cryogenic Sapphire Maser Frequency Standard by Manipulating Fe3+ Spins in the Sapphire Lattice

open access: yes, 2012
To create a stable signal from a cryogenic sapphire maser frequency standard, the frequency-temperature dependence of the supporting Whispering Gallery mode must be annulled.

A multi-color fast-switching microfluidic droplet dye laser [PDF]

open access: yes, 2009
We describe a multi-color microfluidic dye laser operating in whispering gallery mode based on a train of alternating droplets containing solutions of different dyes; this laser is capable of switching the wavelength of its emission between 580 nm and ...

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

open access: yesAdvanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.
