Spectral cleaning and output modal transformations in WGM microresonators
A systematic study on the effects of microtaper fiber diameters on the spectral characteristics of a whisperinggallery-mode (WGM) micro-bottle resonator (MBR) is presented. Progressively cleaner and simpler spectra of the MBR were observed when the utilized microtaper fiber waist diameter (Dt) was increased from 2 μm to 10 μm. The maximum transmission depth at resonance varies with different mi...
متن کاملWhispering 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 کاملUnified approach to mode splitting and scattering loss in high- Q whispering-gallery-mode microresonators
Current theoretical treatments of mode splitting and scattering loss resulting from subwavelength scatterers attached to the surface of high-quality-factor whispering-gallery-mode microresonators are not satisfactory. Different models proposed for distinct scatterer regimes cannot be reconciled. In addition, many experimental results are difficult to understand within the existing theoretical f...
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 ...
