This thesis explores the dynamics and sensing performance of silicon quantum dot (SiQD) ensembles coupled to the whispering gallery modes (WGMs) of spherical and cylindrical microcavities. The first project investigated the possibility of observing Purcell effects in an ensemble of QDs coupled to...

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...
