Silisyum mikroyuvarlar ile ayarlama ve izge gözlemlemesi

Remarkable amount of research is being devoted to the merger of microelectronics and microphotonics on a single silicon chip. Additionally, substantial amount of research has demonstrated a variety of optical functionalities for microspheres. Possessing high quality factor morphology dependent resonances, microspheres have been investigated in resonant cavity enhanced optoelectronic applications. Silicon microspheres, combining the advantage of both the spherical shape and the optoelectronic properties of silicon are ideal candidates for integrated photonics. In this work, silicon microspheres have been excited in the S-band using optical fiber half couplers. The transmission spectra and the elastic scattering spectra from a silicon microsphere have been obtained. Potential difference is applied to the silicon microsphere using two gold electrodes placed on the reciprocal sides of the silicon microsphere. Optical modulation has been observed in both the transmitted and the 90o elastic scattered spectra for the transverse electric and transverse magnetic polarizations. The applied voltage at increasing duty cycles provided promising results about the spectral signature of the morphology dependent resonances.
