Dielectric microspheres are used to resonantly couple light from a half optical fiber coupler to a silicon photodetector. Dielectric microspheres posses high quality factor morphology dependent resonances, i.e., whispering gallery modes. The observed resonances have a channel spacing of 0.14 nm and a linewidth of 0.06 nm. These resonances provide the necessary narrow linewidths, that are needed for high resolution optical spectroscopy applications. Optical communication and biological detection applications of this optoelectronic system are studied experimentally and theoretically.
