Whispering gallery germanium-on-silicon photodetector.
We design and demonstrate, to the best of our knowledge, the first whispering gallery germanium-on-silicon photodetector with evanescent coupling from a silicon bus waveguide in a CMOS-compatible process. The small footprint (63.6 μm2), high responsivity (∼1.04 A/W at 1530 nm), low bias voltage (-1 V), low dark current (2.03 nA), and large optoelectric bandwidth (32.9 GHz) of the detector en...
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 کاملWhispering gallery modes
Whispering gallery modes are specific resonances (or modes) of a wave field that are confined inside a given resonator (cavity) with smooth edges due to continuous total internal reflection. The most interesting from a practical viewpoint are electromagnetic whispering gallery modes, since they posses many unique properties, such as ultra-high Q-factors, low mode volumes, small sizes of resonat...
متن کاملOn-chip nano-optomechanical whispering gallery resonators
This thesis work focuses on the design, fabrication and measurement of Gallium Arsenide (GaAs) nano-optomechanical disk resonators. These disks are both GHz frequency mechanical resonators, and high Q (> 10) optical whispering gallery mode resonators. By confining optical and mechanical energy on a sub-μm volume, they enable extremely large optomechanical coupling strengths (g0 >1 MHz). We pres...
