1. An optical system, the optical system comprising:
an optical source configured to generate a beam of light, wherein the optical source includes a waveguide that amplifies emitted light;
a first modulator configured to slice the beam of light into a plurality of pulses;
a pre-amplifier configured to receive the plurality of pulses from the first modulator and produce pre-amplified plurality of pulses;
a second modulator configured to encode data on the pre-amplified plurality of pulses to produce an encoded plurality of pulses; and
a spectrally-equalizing amplifier configured to receive the encoded plurality of pulses and produce a filtered plurality of pulses, wherein the spectrally-equalizing amplifier spectrally equalizes a gain applied to the encoded plurality of pulses,
wherein the optical system is a remote sensing system.
