Whispering gallery mode resonators for microlasers and microsensors
2005In dielectric spheres light can be guided through high-Q whispering-gallery-modes (WGMs) with an unique combination of strong temporal and spatial confinement of light. Glass microspheres are then of interest for a large number of applications including compact lasers sources and biological sensing.

Freestanding Whispering-Gallery Mode microdisk resonator
The 8th Annual IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2013This article proposes a high-Q value Whispering-Gallery Mode (WGM) microdisk resonator, which is surrounded by photonic crystal with square lattice. Finite element method (FEM) is performed to model the microdisk resonator, and an ultrahigh quality factor (Q) value of 1.37×108 can be achieved at the wavelength of 1435.4nm.

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

Plasmon-enhanced whispering gallery mode biosensing
2012 Photonics Global Conference (PGC), 2012Whispering gallery mode (WGM) biosensors derive their unprecedented sensitivity for label-free detection of biomolecules from the high-quality (Q) factor of an optical resonance phenomenon. Plasmonic excitations in metal nanostructures which are able to localize the WGM field at the target binding site can further enhance sensitivity by local electric ...
