Robert T. Deck (Nonlinear Optics)


       Emeritus Professor of Physics

 Ph.D., 1961, University of Notre Dame


  The communications superhighway in the U.S. is only one of the consequences of the growing field of optical communications.

More broadly, the field covers the entire range of phenomena in which signals are carried by light waves rather than electrical currents. Central to the success of optical communications is the ability to develop suitably miniaturized light switching devices that can rapidly transfer light waves between channels. Dr. Deck, in collaboration with


Dr. Bagley and their graduate students at the University of Toledo, are involved in researching the theory of such light switching devices. The basic elements in these devices are linear and nonlinear directional couplers consisting of side-by-side miniaturized waveguides. The correct fabrication of an array of waveguides requires computation of the design characteristics needed to produce appropriate coupling lengths and switching intensities. In addition to developing an improved theory of the nonlinear directional coupler, Dr. Deck and his collaborators have added to the theory of bending losses in waveguides, and designed filtering and gating devices based on all straight waveguides to simplify the fabrication of signal processing elements.

Work on these projects is continuing.


    In addition Dr. Deck continues his theoretical work related to the foundations of quantum theory.
