electro optic modulation of laser beams

Electro-optic modulators are fast optical amplitude or phase modulators based on the electro-optic effect. Electro-optic amplitude and phase modulators allow you to control the amplitude, phase, and polarization state of an optical beam electrically. For instance, in communications systems, these modulators impress information onto an optical frequency carrier. Unlike direct modulation of the laser itself, external modulators do The Electrooptic and. Acoustooptic Effects and Modulation of Light Beams. In this chapter we shall explain how the distortion produced in a crys- tal lattice by the application of an electric field or by the passage of a sound wave affects the propagation of light through the crystal. These effects – the electrooptic and Thorlabs' free-space electro-optic (EO) amplitude and phase lithium niobate modulators combine crystal growth and electro-optic materials. Our standard modulators use undoped lithium niobate. For higher-power operation, we offer MgO-doped lithium niobate. The standard EO modulators are broadband DC-coupled, and Thorlabs' Lab Facts are dedicated to providing additional information and useful tips for using select products or products lines that are generated by our Applications and Design Engineers through rigorous laboratory testing and analysis. This Electro-Optic (EO) Modulator Lab Fact explains how to extend the functional Electro-optic modulator (EOM) is an optical device in which a signal-controlled element exhibiting the electro-optic effect is used to modulate a beam of light. The modulation may be imposed on the phase, frequency, amplitude, or polarization of the beam. Modulation bandwidths extending into the gigahertz range are make long haul high speed transmission impossible. More importantly, the modulator chirp is dynamic and changes with the actual drive voltage. Another possibility to modulate light is a. Mach Zehnder structure in a material showing strong electro-optic effect (such as LiNbO3 or the 3-5 semiconductors such as GaAs and. This lesson shows how to make a 3D simulation in a material modified by the linear electro-optic effect (Pockels Effect). The waveguide design of Reference [1] is shown in Figure 1 below. In this lesson, this waveguide is created, a potential is applied to the electrodes, and the results are compared to Reference [1].
