Abstract: PROBLEM TO BE SOLVED: To provide a method for optically transmitting data to a remote receiver. SOLUTION: The method for optically transmitting the data to the remote receiver comprises a step of receiving a stream of input data signal, a step of modulating a mid-IR laser by a direct modulation by a waveform having a sequential value corresponding to the stream of the data signals, a step of pumping the mid-IR laser, so as to generate high optical power level corresponding to a different value of the sequential value and a low optical power level from a direct modulation, and a step of transmitting the output signal from the modulated mid-IR laser to the remote receiver via a free space communications channel.

Abstract: 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.
