Title: Michael Digonnet: Innovator in Optical Fiber Technology
Introduction
Michael Digonnet is a prominent inventor based in Palo Alto, California. He has made significant contributions to the field of optical fiber technology, holding two patents that showcase his innovative approaches.
Latest Patents
His latest patents include a method of cladding single crystal optical fibers. This invention details methods and apparatus for cladding grown single crystal optical fibers. Neodymium YAG fibers are clad with a high index glass, either melted around the fiber in a trough or extruded over the fiber surface. Additionally, lithium niobate fibers are clad through an impregnation process. The lithium niobate fiber is first coated with magnesium oxide and then heated to a temperature and for a time sufficient for the magnesium oxide dopant material to diffuse into the fiber. This dopant lowers the intrinsic refractive indices of the fiber material around its circumference, creating a cladding region around the fiber core. Single crystal fibers clad by these methods, combined with suitable pumping means or with deposited electrodes, provide low-loss single mode optical components useful for amplification, electro-optical effects, and acousto-optical effects.
