Abstract
A light intensity modulator includes an input optical fiber; an output optical fiber; an optical arrangement having a lens, where the optical arrangement is configured to receive light from the input optical fiber, pass the light through the lens, and direct the light to the output optical fiber; and a piezoelectric device coupled to the lens, where the piezoelectric device is configured for moving the lens to alter overlap of the output optical fiber and the light directed to the output optical fiber to modulate intensity of light in the output optical fiber.
