Electro-Optic Effect
Electro-optic effect is a change in the refractive index of a crystal as
induced by an electric field. By using a laser amplitude modulator em-
ploying the transverse electro-optic effect of a typical LiNbO3 crystal,
students can conduct the following experiments:
1. understand electro-optic effect and its applications.
2. measure half-wave voltage and electro-optic coefficient of crystals.
3. observe change in optical properties of crystals due to EO effect.
4. observe interference of focused polarized light caused by EO effect.
5. conduct demonstration of laser communication via EO effect.
Note: above product information is subject to change without notice.
1. Study optical axis characteristics of LiNbO3 crystal in absence and presence of driving voltage 2. Observe electro-optic modulation phenomenon 3. Measure half-wave voltage of electro-optic crystal 4. Calculate electro-optic coefficient 5. Demonstrate optical communication using electro-optic modulation technique
