Integrating spheres

Abstract

Spherical microresonators are natural building blocks of three dimensional integrated photonics. The resulting three dimensional device would be a volumetric lightwave circuit or a photonic integrated circuit. The intersphere communication channels can be evanescently coupled optical waveguides. The possible multidimensional integration of these spherical microresonators evanescently coupled with optical waveguides will usher in a new age in integrated photonics and resulting applications and systems.
