Applications of optics in arrays

NASA Lewis has been involved in the development of optical technologies to enable the implementation of millimeter-wave array antennas. The focus of the Lewis research has been in the areas of fiber optic control and RF signal distribution to support MMIC (monolithic microwave integrated circuits) array designs, and the development of optically processed beam forming networks. The development of these optical technologies is being pursued in an effort to enable millimeter-wave communication antenna systems which are limited by the signal distribution systems and antenna system architectures currently available.< >
