Optical label-free detectors, such as the venerable surface plasmon resonance (SPR)
sensor, are generally favored for their ability to obtain quantitative data on intermolecular …

Whispering‐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 …

We show that high-Q whispering-gallery modes in fused-silica microspheres can be
efficiently excited by an optical fiber taper. By adjusting the taper diameter to match the …

We present an optical biosensor with unprecedented sensitivity for detection of unlabeled
molecules. Our device uses optical resonances in a dielectric microparticle (whispering …

SELECTED TOPICS IN QUANTUM ELECTRONICS, VOL. 12, NO. 1, JANUARY/FEBRUARY …

A general model is presented for coupling of high-Q whispering-gallery modes in optical
microsphere resonators with coupler devices that possess a discrete and continuous …

Biosensors based on the shift of whispering-gallery modes in microspheres accompanying
protein adsorption are described by use of a perturbation theory. For random spatial …

Coupling from tapered fibers and polished half-block couplers into the high-Q whispering
gallery modes of microsphere resonators is investigated analytically. Numerous formulas …

For a number of years, the scientific community has been paying growing attention to the
monitoring and enhancement of public health and the quality of life through the detection of …

Reflections that are due to random surface roughness in periodic structures such as
dielectric rings and disks inherently phase match forward-and backward-propagating …
