Optical Modes

This paper addresses the feasibility of an optical vibrometer that is based on the shift of the optical modes, also known as whispering gallery modes (WGMs), of a magnetorheological optical resonator. The optical resonator that is used in this study is fabricated by mixing polyvinyl chloride plastisol with magnetically polarizable particles. When a permanent magnet that is located nearby the optical resonator is moved, it induces a perturbation of the morphology of the resonator, due to the magnetostrictive effect. This change in the morphology induces a shift in the optical modes of the resonator. The shift of the optical modes can be related to the displacement of the permanent magnet. The proposed sensor concept is based on monitoring the displacement of a tiny magnet that is attached to a moving surface. The optical quality factor of the resonator used in these studies was of the order of 106. The experimental results show a sensitivity of 0.32 pm/μm and a resolution that is less than 300 nm.

We fabricated and characterized record small microdisk resonators in thin (210 nm) 3C-SiC film grown on Si (100) substrate. It was found to support high quality factor whispering gallery modes at visible wavelengths. We demonstrated room temperature coupling of these modes to the intrinsic photoluminescence of 3C-SiC at room temperatures and identified their polarization. Finally, we discussed applications for quasi-phasematched second harmonic generation from infrared visible wavelengths.
