Abstract
A system includes at least two optical fibers crossing to form a vertice. The optical fibers comprise a core, a cladding surrounding the core, and a conductive coating at least partially surrounding the length of the cladding. A portion of the core of each of the fibers is exposed proximate to the vertice. An optical microsphere whispering gallery mode (WGM) resonator is positioned to cover exposed core portion of each fiber and in contact with the conductive coating of each fiber. The optical fibers may be orthogonal to each other or offset by a non-orthogonal and non-zero angle. The WGM resonator may be positioned between each of the fibers. An optical energy source may be coupled to an end of the optical fibers, with an optical detector coupled to the other end. A voltage source may be connected to the conductive coating of each of the optical fibers.
