Voltage Controlled Micro Cavity-Waveguide Coupling for Switching, Routing, and Modulation of Optical Waves

Abstract

We report that greater than 99.89 % optical power transfer to whispering-gallery modes was achieved in fused-silica microspheres by use of a dual-tapered-fiber coupling method. The intrinsic cavity loss and the taper-to-sphere coupling coefficient are inferred from the experimental data. It is shown that the low intrinsic cavity loss and the symmetrical dual-coupling structure are crucial for obtaining the high-coupling efficiency.
