0627003800 is a generic name for an electro-optical modulator. The modulator finds widespread application in today\'s world ranging from telecom/broadcasting, medical imaging, defense/aerospace to consumer electronics etc. and is essential in enabling sensing, switching and communication capabilities for an ever-increasing range of applications. A typical usecase of an electro-optical modulator is transmission of data from a satellite to an earthbound station.

An electro-optical modulator (EOM) operates on the principle of light modulation by an external electric field. It is basically an optical device that is typically used to modulate an optical signal in response to an electrical signal. This is typically achieved by an interaction between the electric field produced by the electrical signal and the optical waveguide within the electro-optic material, in which this electric field is applied. This interaction results in phase or amplitude change of the optical waveguide, which is then converted into an electrical wave. The electrical wave can then be used for various applications such as data transmission, communication, signal processing etc.

An electro-optical modulator can be made from various materials such as silicon, gallium arsenide, indium phosphide and titanium dioxide. Each of these materials has its own unique properties and offers varying levels of light modulation. Each material offers different advantages and can be used for different applications.

For instance, silicon is well suited for integration into CMOS-based chip sets. Also, it can offer fast switching speeds. Gallium arsenide is an expensive material, but offers superior switching speeds and high power dissipation capabilities. Titanium dioxide is used in optoelectronic devices for optical switching and signal processing applications. It provides fast and efficient optical switching and modulation.

The various components of an electro-optical modulator include the optical waveguide (also referred to as the "active" component) and electrical control circuitry. The optical waveguide is constructed of an electro-optic material such as a semiconductor or dielectric material. This wave guide interacts with the external electric field causing the light waveguides to either increase or decrease its amplitude, depending on the strength of the applied electric field. The electrical control circuitry is used to control the direction and magnitude of the electric field and to determine the intensity of the emitted light wave.

In addition to the application of electro-optical modulators in telecom/broadcasting, medical imaging, defense/aerospace and consumer electronics, they can also find application in other areas like optical storage, optical networks and optical computing. EOMs are also used in spectroscopy and laser-based medical treatments. With an increasing range of applications, the demand for electro-optical modulators is also increasing rapidly.

To sum up, electro-optical modulators are used for a wide range of applications ranging from telecom/broadcasting, medical imaging, defense/aerospace to consumer electronics. They operate on the principle of light modulation by an external electric field and can be made from a variety of materials. Their components include optical waveguides and electrical control circuitry which allows for light intensity modulation. With their varied applications, EOMs are quickly becoming an essential component in enabling sensing, switching and communication capabilities.
