Title: Optical modulator and optical modulation method
Inventor: ENOTANI JUN
IPC: G02F1/35
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To obtain a constantly modulated light by changing the refractive index of a nonlinear optical crystal at the time of allowing the nonlinear optical crystal to change the outgoing light from a polarizer which emits a light by rotating the plane of an incident light to the modulated light to emit the modulated light and at the time of emitting lights from another polarizer by lining up planes of polarization of this outgoing lights. SOLUTION: The plane of polarization of an incident light 6 emitted from a light source 1 is rotated by a first polarizer 2 and it is made to be a linearly polarized light whose direction of the plane of polarization is vertical with respect to the axis of the incident light 6 to be incident on a nonlinear optical crystal 3. The linearly polarized light is changed into a modulated light in the nonlinear crystal 3 to be emitted to a second polarizer 4, which lines up planes of polarization of outgoing lights from the crystal 3 to emit them. Here, an external power source 5 generates a high frequency electric field in the crystal 3 by impressing a high frequency wave on the crystal 3 to change the refractive index of the crystal 3 by the high frequency electric field.  Thus, the light intensity of a return light can be suppressed with a simple consitution and it is eliminated that the return light affects the light source.
