Cam mikroyuvarların amorf ve kristal sıvılar içinde optik çınlamaları

Optical microcavities have found many applications in linear optics, nonlinear optics, quantum optics, and biophotonics as laser light sources as well as optical switching, sensing, and wavelength division multiplexing devices. Microspheres are high quality factor optical microcavities that localize light by total internal reflection. Electromagnetic boundary conditions have to be satisfied for the light localization. Optical resonances occur, when an integer multiple of the wavelength is equal to the optical pathway of the cavity.In this work, the polarization dependence of the optical resonances in an optical fiber- microsphere system is investigated experimentally. The change of the elastic light scattering spectra of the microspheres is studied for microspheres placed in various fluids. It is observed that, the shape of resonances and the intensity of the background are strongly dependent on the surrounding fluid medium. Blue and red shifts of the optical resonances are observed due to the changes of the external fluid media. This optical geometry heralds new device designs and applications for microsphere based optoelectronics and microfluidics.
