<p>PROBLEM TO BE SOLVED: To provide an optical shutter which has a simple structure, is easily manufactured, has a structure enabling miniaturization, and can be operated by a low half wavelength voltage. SOLUTION: In the optical controller which has flat electrodes formed on a surface where the light of a transparent electrooptic effect device is made incident and on its opposite surface, an electric field is applied so that the direction of the electric field is inclined relative to an optical path.</p> |
