This work develops a refractive-index sensor based on whispering gallery modes (WGMs) in glass microcapillaries. The capillary channel is coated with a layer of fluorescent silicon quantum dots (QDs), which provides a fluorescence source that also supports the WGMs. When different fluids are...

Whispering gallery modes in layered microspheres: mode structure, thermal response, and reactive sensing
DownloadFall 2014
This thesis focuses on the physics of the whispering gallery modes (WGMs) of silica microspheres coated with a layer of fluorescent silicon quantum dots (Si QDs). The basic theory associated with these structures was explored, and we showed how the important physical parameters such as the...
