Experimental System for Electro-Optic Modulation 

Acousto-optic effect refers to the phenomenon of diffraction of light through a medium which is disturbed by ultrasound. This phenomenon is the result of interaction between light waves and acoustic waves in the medium. The acousto-optic effect provides an effective means to control the frequency, direction and strength of the laser beam. Acousto-optic devices made by acousto-optic effect, such as acousto-optic modulator, acousto-optic deflector and tunable filter, have important applications in laser technology, optical signal processing and integrated optical communication technology.

Experiment Examples 

1. Display electro-optic modulation waveform

2. Observe electro-optic modulation phenomenon

3. Measure half-wave voltage of an electro-optic crystal

4. Calculate electro-optic coefficient

5. Demonstrate optical communication using electro-optic modulation technique
