Abstract

A new technique of generating true-time-delay phase shifts of broadband microwave and millimeter-wave signals through optical control has been demonstrated. Continuous and precise phase shift with a range of 360 degrees has been achieved without millimeter-wave signal loss. The microwave/millimeter-wave circuit and the optic-electronic intermixing structure can be monolithically integrated. Optical fiber distribution of the picosecond triggering pulses could be applied. The potential applications of this optical control technique are in phased-array radar and satellite-borne communication systems.<>
