Semiconductor Optical Amplifier (SOA)
A Semiconductor Optical Amplifier (SOA) is a device that boosts the strength of light signals in fiber optic communications. It uses semiconductor materials, much like those found in computer chips, to amplify light rather than electric current. When a weak light signal passes through the SOA, it stimulates the semiconductor to release more light at the same wavelength, effectively amplifying the original signal. This technology enhances data transmission over long distances, improves signal quality, and is crucial in telecommunications and data centers, making it easier to send large amounts of information quickly and efficiently.
