What Is an Acousto-Optic Modulator?
An acousto-optic modulator is a device used to encode audio signals into optical signals, playing a crucial role in optical communication and audio transmission systems.
This modulator converts audio inputs, typically from microphones, into electrical signals, which are then transformed into optical signals. This conversion process is essential for transmitting information through optical fibers.
All acousto-optic modulators operate by manipulating light intensity, phase, or frequency to carry audio information. Their significant benefit is leveraging optical fibers’ wide bandwidth, enabling fast and voluminous data transmission while reducing susceptibility to electromagnetic interference and noise.
