ABSTRACT We demonstrate a scalable and reconfigurable optical directed-logic architecture consisting of a regular array of integrated optical switches based on microring resonators. The switches are controlled by electrical input logic signals through embedded p-i-n junctions. The circuit can be reconfigured to perform any combinational logic operation by thermally tuning the operation modes of the switches. Here we show experimentally a directed logic circuit based on a 2×2 array of switches. The circuit is reconfigured to perform arbitrary two-input logic functions.

    ABSTRACT: We present an expanded all-optical programmable logic array (O-PLA) using multi-input and multi-output canonical logic units (CLUs) generation. Based on four-wave mixing (FWM) in highly nonlinear fiber (HNLF), two-input and three-input CLUs are simultaneously achieved in five different channels with an operation speed of 40 Gb/s. Clear temporal waveforms and wide open eye diagrams are successfully observed. The effectiveness of the scheme is validated by extinction ratio and optical signal-to-noise ratio measurements. The computing capacity, defined as the total amount of logic functions achieved by the O-PLA, is discussed in detail. For a three-input O-PLA, the computing capacity of the expanded CLUs-PLA is more than two times as large as that of the standard CLUs-PLA, and this multiple will increase to more than three and a half as the idlers are individually independent.

    ABSTRACT: We present designs of all-optical ultrafast YES/NOT, XOR/XNOR logic gates, binary counter, and double-bit comparator based on all-optical switching by two-photon absorption induced free-carrier injection in silicon 2×2 add–drop microring resonators. The proposed circuits have been theoretically analyzed using time-domain coupled-mode theory based on reported experimental values to realize low power (∼28 mW) ultrafast (∼22 ps) operation with high modulation (80%) and bit rate (45 Gb/s). The designs are complementary metal-oxide semiconductor compatible and provide advantages of high Q-factor, tunability, compactness, cascadibility, scalability, reconfigurability, simplicity, and minimal number of switches and inputs for realization of the desired logic. Although a two-bit counter has been shown, the scheme can easily be extended to N-bit counter through cascading.

    ABSTRACT: Simultaneous logic and its inverse in a single circuit is an important design because input data of a circuit cannot be lost during operation. In this manuscript an optical microelectromechanical system (MEMS) based diagonal switching architecture is proposed and described by which simultaneous n-variable XOR/XNOR are shown. Also numerical simulations have been done to get the performance of the logic unit.
