    We describe five classes of smart pixel devices with increasing complexity and present an optoelectronic integrated circuit (OEIC) smart pixel array having programmable amplifier, inverter, logic element, bistable switch or latch functions. These devices are used in transmissive and reflective architectures to implement reconfigurable processors, multiplexed shuffle networks, cellular hypercube processors or sorting networks.</jats:p

    Integrated, asymmetric twin-waveguide ultrafast all-optical switch

    The monolithic integration of a terahertz optical asymmetric demultiplexer (TOAD) in an asymmetric twin-waveguide structure is demonstrated. Signal switching is accomplished via nonlinear gain compression and phase shifts in the semiconductor optical amplifiers (SOAs) induced by a control pulse propagating in the direction opposite that of the signal
