Acousto-optics modulator: AOM Fiber-coupled acousto-optic devices are available at various wavelengths from 380nm to 2500nm.
Optical modulators are used in optical communication systems to encode data onto light waves for transmission through optical fibers. The beam may be carried over free space, or propagated through an optical waveguide (optical fibre). Fibers consist of three primary components: the core, cladding, and coating. ptic fibres provide a far higher bandwidth. Amplitude Shift Keying (ASK) is a digital modulation technique that represents binary data by shifting the amplitude of a carrier wave among discrete levels. Light itself is a single waveform and cannot directly carry complex information.
