DATA TRANSMISSION VIA DIRECT MODULATION OF A MID-IR LASER

摘要

A process for optically transmitting data to a remote receiver includes receiving a stream of input data signals and modulating a mid-IR laser by direct modulation with a waveform whose sequential values are responsive of the dat a signals of the stream. The direct modulation includes pumping the mid-IR las er to produce high and low optical power levels in response to different ones of t he values. The process also includes transmitting output light from the modulated mid-I R laser to the remote receiver via a free space communications channel.
