Whispering gallery mode microresonators: Fundamentals and applications
— Confinement of light into small volumes has become an essential requirement for photonic devices; examples of this trend are provided by optical fibers, integrated optical circuits, semiconductor lasers, and photonic crystals. Optical dielectric resonators supporting Whispering Gallery Modes (WGMs) represent another class of cavity devices with exceptional properties, like extremely small mod...
متن کاملWhispering Gallery Mode Thermometry
This paper presents a state-of-the-art whispering gallery mode (WGM) thermometer system, which could replace platinum resistance thermometers currently used in many industrial applications, thus overcoming some of their well-known limitations and their potential for providing lower measurement uncertainty. The temperature-sensing element is a sapphire-crystal-based whispering gallery mode reson...
متن کاملWhispering Gallery Mode Biosensor
sensor which uses whispering gallery modes (WGMs) in dielectric microspheres for biomolecular detection. The WGMs are excited by evanescent coupling to an etch-eroded single mode optical fiber. WGM resonance positions are detected as Lorentzian dips in the intensity of the fiber-transmitted light. The polarization of molecules interacting with the evanescent field of the WGM on the microsphere ...
متن کاملSimulation of Whispering-gallery Mode Microsensing in a Microfluidic System
Label-free detection using a whispering-gallery model biosensor in a micro fluidic channel is simulated. The analyte transport in the solution is controlled by applied electric potentials and diffusion. The finite element method is employed for solving the charged species transportation equations, the Poisson equation, the equations of conservation of momentum and energy, and the Helmholtz equa...
متن کاملSimulation of Whispering-gallery-mode Resonance for Optical Miniature Biosensor
A finite element analysis is made of the shifts of resonance frequencies of whispering-gallery-mode (WGM) for a fiber-microsphere coupling miniature sensor. The timedomain Maxwell’s equations were adopted to describe the near-field radiation and solved by the Inplane TE waves application mode of the FEMLAB. The electromagnetic field as well as the radiation energy distribution can be easily obt...
