Abstract:
Optical systems and methods for transmission of multiple beams and direct detection of those beams are described. One transmitter for use in a free space optical communication system includes a broad spectrum light source and an optical component including a plurality of sections positioned to receive an optical beam produced by the broad spectrum light source. The sections of the optical component are formed to introduce optical path differences into portions of the optical beam that impinge on the optical component such that each section introduces a delay into a corresponding portion of the optical beam. The introduced delays cause each portion of the optical beam to lack coherence with other portions of the optical beam. A direct detection receiver detects the intensity of the aggregate beams and produces a signal with improved signal-to-noise ratio. The disclosed technology can be used with modulated optical beams such as intensity modulated beams.

Claim (Index 19):
A free space optical communication system, comprising:\n a transmitter, comprising:\n a broad spectrum light source; and \n an optical component including a plurality of sections and positioned to receive an optical beam produced by the broad spectrum light source, wherein:\n the plurality of sections are formed to introduce optical path differences into portions of the optical beam that impinge on the optical component such that each section introduces a delay into a corresponding portion of the optical beam that is different from a delay introduced into other portions of the optical beam by other sections of the optical component, and \n \n the delays introduced by the plurality of sections cause each portion of the optical beam that impinges on a corresponding section of the optical component to lack coherence with other portions of the optical beam that impinge on other sections of the optical component; and \n a receiver positioned to receive a plurality of the portions of the optical beam that exits the optical component and propagates through atmosphere, the receiver including a photodetector to sense an intensity of the received plurality of the portions of the optical beam, wherein the optical beam received by the optical component comprises a modulated optical beam having a modulation rate, r, and wherein the broad spectrum light source has a spectral bandwidth that is larger than r.
