を特徴とする光変調器。In an optical modulator that modulates light incident on a photodetector by vibration of a piezoelectric vibrator having a modulation means and guides the light to the photodetector, the piezoelectric vibrator is composed of a piezoelectric element and an elastic plate,
The tip of this elastic plate is extended and bent at right angles, and the tip is alternately formed with required light-shielding parts and light-transmitting parts to form a movable slit, and the movable slit is provided opposite to the movable slit. An optical modulator characterized in that a modulation means is formed by a fixed slit plate.
