Abstract
An optical communication system for free space communication includes an optical source including a modulator to modulate the optical output to provide an optical signal. The optical source is connected to an optical fiber to pass the signal therealong. The optical fiber includes an antenna having an optical fiber transmit portion with a core, and a cladding, the cladding including at least one substantially flat surface extending along its length and arranged to couple light out of the optical fiber through the substantially flat surface(s). A scattering structure scatters into free space light thus coupled out of the fiber.
