An Electro-Absorption Modulator (EAM) is an opto-electronic device used to modulate light signals transmitted through optical cables. It is a semiconductor diode reverse-modulated so it modulates the intensity of light passing through it. The EAM is based on the principle of changing the absorption of light in a semiconductor diode when an electric field is applied.
The EAM is commonly used in optical communication systems to modulate the intensity of the light transmitted through the optical cable. It is used to transmit data between two points using the modulation of light.
The EAM is usually used in applications such as fiber-optic cables, radio-over-fiber systems, and optical communication systems. The EAM is also used in the modulation of optical signals by modulating the absorption of light in a semiconductor diode. The EAM is capable of operating at a wide range of frequencies, with high speed and low power consumption.
The EAM is made up of two components: a semiconductor diode and an optical modulator. The electrical field applied to the diode changes the absorption of light in the diode, which in turn modulates the intensity of light passing through the optical cable. The modulation of light is then used to transmit data from one point to another.
The EAM is a low-cost, high-performance device that is used in many applications. Its ability to modulate light signals makes it a popular choice for optical communication systems. It is also used in the modulation of optical signals for various applications such as fiber-optic cables, radio-over-fiber systems, and optical communication systems.
