Experimental System for Electro-Optic Modulation for Lasers and Photonics Physics Lab

The Experimental System for Electro-Optic Modulation for Lasers and Photonics Physics Lab is designed to demonstrate the electro-optic effect in a crystal, where the refractive index changes under the influence of an applied electric field. The system utilizes a Lithium Niobate (LiNbO₃) crystal, a widely used electro-optic material known for its strong Pockels effect, enabling efficient modulation of light. The apparatus allows students to investigate the interaction between electric fields and polarized light, observe electro-optic modulation phenomena, and measure important electro-optic parameters. Through practical experiments, users can gain a deeper understanding of optical modulation techniques used in modern communication systems, laser technology, and photonic devices. The system serves as an excellent educational platform for studying electro-optic materials, modulation principles, and optical signal transmission technologies.
