Since its inception in 1992, DARPA’s Microsystems Technology Office (MTO) has helped create and prevent strategic surprise through investments in compact microelectronic components such as microprocessors, Microelectromechanical systems (MEMS), and photonic devices. MTO’s revolutionary work applying advanced capabilities in areas such as wide-band gap materials, phased array radars, high-energy lasers and infrared imaging have helped the United States establish and maintain technological superiority for more than two decades.
