Free Space Optical Communication Terminal with Dispersive Optical Component

A local free space optical (FSO) communication terminal configured to transmit optical beams to and receive optical beams from a remote FSO communication terminal, the local FSO communication terminal comprising:

• a fore optic having a focal plane, wherein a receive (Rx) optical beam from the remote FSO communication terminal is received and focused by the fore optic to a Rx spot at the focal plane and a transmit (Tx) optical beam forms a Tx spot at the focal plane and is collimated and projected by the fore optic to the remote FSO communication terminal;
• and
• a dispersive optical component that is positioned along optical paths of both the Rx optical beam and the Tx optical beam, wherein the Rx and Tx optical beams are different wavelengths and a wavelength dependence of the dispersive optical component laterally separates the Rx spot and the Tx spot at the focal plane.
