1. An optical system, the optical system comprising:
an optical source configured to generate a first beam of light,
wherein the optical source includes a waveguide that amplifies emitted light, and
the first beam of light has a first signal-to-noise ratio; and
an optical amplifier,
wherein the optical amplifier is configured to receive the first beam of light, directly or indirectly, from the optical source and produce a second beam of light,
the second beam has a second signal-to-noise ratio,
the second signal-to-noise ratio is at least three times as large as the first signal-to-noise ratio, and
wherein the optical system is configured to transmit the second beam of light, through a variably refractive medium, to a detector having a photoreceiver,
wherein the first beam of light is configured to encode a bit in a given time slot by not emitting the emitted light in that time slot or emitting the emitted light in less than 50% of the given time slot.
