Coated spherical microresonators for cutting-edge photonics application
Résumé
We present some results regarding the coating of spherical microresonators and their different applications in photonics. The spherical microresonators high Q-factor and low mode volume make them perfect for a number of photonics applications. A thin film coating on the surface of the resonator using an optically active or passive layer can be used to modify signifactly the optical properties of the resonator. We have succesfully coated the microresonators with a sol-gel derived coating and have studied the effect of the coating on different optical and spectroscopical properties of the microresonator.
