Abstract
At the present time phase modulation in optical fiber systems for communication, devices such as all-fiber gyroscopes, and active compensators for Mach-Zehnder interferometers in fiber optic sensors, is accomplished by using piezoelectric cylinders with wrapped fibers. However, the PZT cylinder cannot be modulated at high frequencies (above ~ 1 MHz), and also also its weight and size is a disadvantage. Elasto-optic interaction and modulation of the light beam propagating in an optical fiber in the MHz region would be extremely desirable for such applications as: heterodyning, active compensator schemes, small fiber gyroscopes and other devices.
