All-polymer whispering gallery mode sensor for application in optofluidics
Microcavities such as spheres or rings are resonant optical sensors which support whispering gallery modes (WGMs). In recent years WGM based sensors have been continuously improved with respect to sensitivity and detection limit. The conventional method to measure physical as well as biological quantities using WGMs is to record the resonance shift of a single resonator. To ensure high sensitiv...
متن کاملAll-polymer whispering gallery mode sensor in the low-Q regime
Microcavities, such as spheres, rings or toroids, show sharp optical resonances at specific wavelengths, called whispering gallery modes (WGMs). They correspond to light waves circling around the cavity, relying on continuous total internal reflection at the cavity surface. After one roundtrip, the light waves return to the same point with the same phase, hence interfere constructively with the...
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 کاملTuning Whispering Gallery Mode Lasing from Self-Assembled Polymer Droplets
Optical microcavities are important for both fundamental studies of light-matter interaction and applications such as microlasers, optical switches and filters etc... Tunable microresonators, in which resonant modes can be manipulated, are especially fascinating. Here we demonstrate a unique approach to mechanically tuning microresonators formed by polymer droplets with varying sizes. The dropl...
