Whispering 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 کاملWhispering-gallery mode microdisk lasers
A new microlaser design based on the high-reflectivity whispering-gallery modes around the edge of a thin semiconductor microdisk is described and initial experimental results are presented. Optical confinement within the thin disk plane results in a microresonator with potential for single-mode, ultralow threshold lasers. Initial experiments use selective etching techniques in the InP/InGaAsP ...
متن کاملWhispering-gallery mode terahertz pulses.
We report what is to our knowledge the first observation of a subpicosecond terahertz (THz) pulse propagating as a superposition of the whispering-gallery modes (WGMs) of a dielectric cylinder. The WGM THz pulses are coupled into and out of a 5-mm-diameter silicon cylinder via a 100-mum -thick, single-mode silicon slab waveguide. We observed two round-trip cylindrical cavity pulses from this co...
متن کاملBack-scatter based whispering gallery mode sensing
Whispering gallery mode biosensors allow selective unlabelled detection of single proteins and, combined with quantum limited sensitivity, the possibility for noninvasive real-time observation of motor molecule motion. However, to date technical noise sources, most particularly low frequency laser noise, have constrained such applications. Here we introduce a new technique for whispering galler...
