Paper Abstract

The possibility of forming a surface wave electro-optic modulator is considered. Such a device is formed by launching a surface electromagnetic wave on an optical planar guide. A grating can be formed via the electro-optic or Kerr effect. Similar to the surface acoustic wave device, depending on the frequency and strength of the the modulation signal, it can deflect the incoming optical beam. However, different from a surface acoustic wave device, the surface wave electro-optic modulator is supposed to work at multi-gigahertz frequencies. In order to have a large deflection angle and a high efficiency, one needs a substrate which can support an electromagnetic modulation signal that is tightly confined to the surface and has a very slow phase velocity. Various materials, phenomena, and structures are considered. The advantage and disadvantage of each are discussed.
