Abstract
Various embodiments for a system and method for a range-enhanced high-speed free-space optical communication are described herein. Generally, the optical communication system may include a first modulator, a second modulator and an average-power limited optical amplifier. The first modulator may receive an input optical signal and generate a modulated optical signal. The second modulator may receive the modulated signal and may be operable to turn-off a select number of pulses in each modulated pulse frame of the modulated signal to generate a low-duty cycle modulated signal. The average-power limited optical amplifier may then generate an amplified modulated signal from the low-duty cycle signal, wherein the amplified modulated signal comprises a plurality of amplified pulse frames with each amplified pulse frame defining an amplified version of a corresponding each low-duty cycle pulse frame.
