Notice that if one modulates the amplitude instead of the phase, moulator gets only the first set of sidebands. Particular functionality may be common to several products.

Notice however that we only used the first term in the Taylor expansion – in truth there are an infinite number of sidebands. This page was last edited on 30 Octoberat Generally, a nonlinear optical material organic polymers have the fastest response rates, and thus are best for this application with an incident static or low frequency optical field will see a modulation of its refractive index.

The phase of a carrier signal is modulated to follow the changing voltage level amplitude of modulation signal. The polarization change measured by such techniques is linearly dependent on the electric field applied to the crystal, hence provides absolute measurements of the field, without the need for numerical integration of voltage traces, as is the case for conductive probes sensitive to the time-derivative of the electric field.

Electro-optic modulator

Furthermore, this example may also be defined and modeled using components from the following product combinations:. Modulation bandwidths extending into the gigahertz range are possible with the use of laser -controlled modulators. Fanglu Lu, Thai-Truong D.

Suggested Products Download the application files This model example illustrates applications of this type that would nominally be built using modulafor following products: You can fix this by pressing ‘F12’ on macn-zehnder keyboard, Selecting ‘Document Mode’ and choosing ‘standards’ or the latest moodulator listed if standards is not an option. Changing the electric field on the phase modulating path will then determine whether the two beams interfere constructively or destructively at the output, and thereby control the amplitude or intensity of the exiting light.

Liquid crystal devices are electro-optical phase modulators if no polarizers are used. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license.

The analysis and the final result modulated signal are similar to those of frequency modulation.

The input waveguide is mach-zehnderr up into two waveguide interferometer arms. Van Thourhout, and G. From Wikipedia, the free encyclopedia. Optical devices Nonlinear optics. A beam splitter divides the laser light into two paths, one of which has a phase modulator as described above.

This is caused by forces that distort the position, orientation, or shape of the molecules constituting the material.

Furthermore, this example may also be defined and modeled using components from the following product combinations: Electro-optic modulator EOM is an optical device in which a signal-controlled element exhibiting the electro-optic mach-zehder is used to modulate a beam of light.

This adds a time dependent phase to the above expression. Privacy Terms of Use.

Electro-optic modulator – Wikipedia

A very common application of EOMs is for creating sidebands in a monochromatic laser beam. For a Pockels cell, it is usually hundreds or even thousands of volts, so that a high-voltage amplifier is required.

A Pockels cell can thus be seen as a voltage-controlled waveplate, and it can be used for modulating the polarization state.

The electro-optic effect is the change in the refractive index of a material resulting from the application of a DC or low-frequency electric field.
