Signal device employing photorefractive area modulation |
摘要 |
A variable area recording geometry is formed over the surface of a photosensitive material by scanning and exposing with an optical writing beam. The width of this area is determined by input signals to be processed. The exposed photorefractive medium results in a phase modulation of an optical beam traversing the medium in a direction parallel to the surface as in an integrated optical waveguide.
