Abstract
An optically phased conformal antenna and photonic interconnect therefor that may be used in such microwave systems. Rows of microwave circuits are disposed on top of a cooling arrangement disposed on a curved surface. An optical ribbon cable disposed on top of the microwave circuits is employed to couple signals to the microwave circuits. Microwave antennas are disposed on top of the optical ribbon cable which has windows therein that permit welding of the antennas to the appropriate microwave circuits. Optical coupling of signals from the optical cable to the microwave circuits is achieved through the use of diffraction gratings, and the like, formed in the optical cable, in conjunction with laser diodes and detectors disposed on the chips.
