Experimental System for Crystal Electro-Optic Modulation
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 employing the transverse electro-optic effect of a typical LiNbO3 crystal, students can
1. understand electro-optic effect and its applications
2. be able to measure the half-wave voltage and electro-optic coefficient of crystals
3. observe a change in optical properties of crystals due to electro-optic effect
4. observe the interference of focused polarized light as caused by electro-optic effect
5. 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
Application
Including He-Ne laser with power supply
Precise optical alignment
Observe and measure electro-optic modulation waveform
High sensitivity photoreceiver for stable waveform output
