Abstract
A device that controls and reshapes optical signals generated by a laser or sent through fiber optic cables for eventual broadcast to various sectors. The optical train transforms the input Gaussian beam into a flat-top beam, a beam with a uniform intensity distribution. The device can operate either in a super broadband sector spectral output mode, which is a combination of independent orders of diffraction, or be extended to operate as a multi-beam system, where spatially separated beams are obtained at the output of the transmitter. In accordance with aspects of the present invention, both the point-to-sector and multi-beam schemes can be obtained from a single source.
