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 that employs the transverse electro-optic effect of a typical LiNbO3 crystal, students can
a.understand electro-optic effect and its applications
b.be able to measure the half-wave voltage and electro-optic coefficient of crystals
c.observe a change in optical properties of crystals due to electro-optic effect
d.observe the interference of focused polarized light as caused by electro-optic effect
e.conduct experimental demonstration of laser communication.
This experimental system can be used to conduct the following experiments:
1.Display electro-optic modulation waveform
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
