A novel all-optical logic device, composed of an SOA and an optical filter, is demonstrated for AND, OR and XOR gates at 10 Gb/s. Simulation indicates the device can operate at much higher bit rate.
The IST-LASAGNE project aims at designing and implementing the first, modular, scalable and truly alloptical photonic router capable of operating at 40 Gb/s. The main results achieved in the project are presented in this paper, with emphasis on the implementation of network node functionalities employing optical logic gates and optical flip-flops, as well as an economical study on the proposed ...
We experimentally demonstrate an all-optical binary counter composed of four semiconductor optical amplifier based all-optical switching gates. The time-of-flight optical circuit operates with bit-differential delays between the exclusive-OR gate used for modulo-2 binary addition and the AND gate used for binary carry detection. A movie of the counter operating in real time is presented.
Experimental Realization of Topologically-Protected All-Optical Logic Gates Based on Silicon Photonic Crystal Slabs In article number 2200329, Furong Zhang, Lu He, Huizhen Xiangdong and colleagues present the experimental realization topologically-protected all-optical logic gates Chips. All major functions (OR, XOR, NOT, XNOR, NAND, NOR, AND) can be realized even if some disorders exist. These...
Quantum computation offers potential advantages in solving a number of interesting and difficult problems. Several controlled logic gates, the elemental building blocks of quantum computer, have been realized with various physical systems. A general technique was recently proposed that significantly reduces the realization complexity of multiple-control logic gates by harnessing multi-level inf...
We present experimental results on a new method for ultrafast all-optical logic, which utilizes four-wave mixing on polarization-modulated signals. The technique allows advanced operations such as exclusive-or and three-bit addition with carry bit. Furthermore, we show that on-the-fly error-correction encoding and decoding of a simple Hamming code is achieved when these gates are used on the bi...
