We propose a method of magnetic-field tuning whispering gallery modes (WGMs) based on a hollow microbubble resonator (HMBR) with Terfenol-D-fixed. WGMs are excited by the evanescent field from a tapered fiber coupling with an HMBR.

2D-material-integrated whispering-gallery-mode microcavity
Photonics Research, 2019Optical microcavities, which support whispering gallery modes, have attracted tremendous attention in both fundamental research and potential applications. The emerging of two-dimensional materials offers a feasible solution to improve the performance of

Active mode locking with whispering-gallery modes
Journal of the Optical Society of America B, 2003We theoretically propose an architecture of a whispering-gallery mode-locked laser with an integrated intracavity microphotonic electro-optic modulator based on an Er:LiNbO3 disk resonator. The laser promises to be small in size, to have a high pulse repetition rate, and to use a small amount of microwave power.

Whispering gallery mode aptasensors for detection of blood proteins
Journal of Biophotonics, 2012AbstractWhispering gallery mode resonators (WGMR), as silica microspheres, have been recently proposed as an efficient tool for the realisation of optical biosensors. In this work we present a functionalization procedure based on the DNA‐aptamer sequence immobilization on WGMR, able to recognize specifically thrombin or VEGF protein, preserving a high ...

Whispering-gallery modes of dielectric resonators
IEE Proceedings H Microwaves, Optics and Antennas, 1982The whispering-gallery modes of cylindrical dielectric resonators of high permittivity (er~38) are investigated. Axial-mode confinement is ensured by a slight increase in the rod diameter. The resonances for various azimuthal mode numbers and the two states of polarisation are identified experimentally.

Aptamer Based Whispering Gallery Mode Biosensor
2013Whispering gallery mode resonators (WGMR), in the form of optical silica microspheres, have been recently proposed as an efficient tool for the realisation of optical biosensors. A crucial step for producing reliable biosensors is their surface functionalization. In this work we report a functionalization process based on the use of a DNA aptamer. Also

Mode Selection for a Whispering Gallery Mode Resonator
29th European Microwave Conference, 1999, 1999An original mode selection technique for whispering gallery mode sapphire resonator (WGMR) is presented. A set of metallic screws, inserted in the cavity, allows to improve the frequency isolation of the WGEm,0,0 modes, with little Q-factor degradation. The design has been performed using a 3-D Finite Element Method (FEM) software to check the validity
