High speed data link and transmitter in the mid-infrared wavelength range

摘要

A mid-infrared transmitter for providing a light signal in a free-space communication system includes an arrangement for producing electromagnetic radiation having a certain wavelength in a mid-infrared wavelength range. The mid-infrared transmitter further includes an arrangement for modulating the electromagnetic radiation so as to provide a train of light pulses having the certain wavelength as the light signal.
