All‐optical logic gates using colloids

Microwave and Optical Technology Letters, 1988
AbstractAn all‐optical technique is used to realize three logic operations, AND, X‐OR, and NOT. The logic inputs are represented by laser beams that are made to cross in a sample of polymer microspheres at predetermined angles.

Invertible all-optical logic gate on chip

Optics Letters
We demonstrate an invertible all-optical gate on chip, with the roles of control and signal switchable by slightly adjusting their relative arrival time at the gate. It is based on the quantum Zeno blockade (QZB) driven by sum-frequency generation (SFG) in a periodically poled lithium niobate microring resonator.

Design of all optical reversible logic gates

2014 International Conference on Communication and Signal Processing, 2014
Considering the benefits of Quantum and Optics, if the logic gates in the quantum field and electronic structure are implemented using optical elements, then it will be benefited from advantages of Quantum and design, and these processing circuits can be used in optical computing and quantum computing, genetic processes, and other useful nanotechnology

Simple ultrafast all-optical AND logic gate

Optical Engineering, 2007
A simple scheme for an all-optical AND logic gate is proposed based on a sagnac interferometric structure. The operations of this scheme with a 40-Gbit/s return-to-zero (RZ) pseudorandom bit stream (PRBS) are simulated correctly with an output extinction ratio (ER) of about 14.7 dB.

Robustness of scalable all-optical logic gates

CLEO: 2014, 2014
We designed scalable all-optical logic gates that operate at the same input and output wavelength based on microrings. We investigated the influence of input power fluctuations and fabrication errors.

All-optical quaternary logic gates

Journal of Modern Optics, 2013
Conventional binary logic based operations restrict the speed of operations as well as information handling capacity. A way to overcome these limitations is the implementation of multivalued logic operations in the optical domain. Multivalued logic operations not only enhance the data handling capacities but also increase the speed of processing ...

All-Optical Single-Channel Plasmonic Logic Gates

Nano Letters
Optical computing, renowned for its light-speed processing and low power consumption, typically relies on the coherent control of two light sources. However, there are challenges in stabilizing and maintaining high optical spatiotemporal coherence, especially for large-scale computing systems.

An Ultrafast GaAs All-Optical Logic Gate

1986
Optical bistable devices and logic gates show considerable promise for image and data processing. Non-linear semi-conductor etalon devices have become increasingly popular for research on switching at low powers and high speeds. In this respect gallium arsenide and related multiple-quantum-well structures (MAWS) have displayed an interesting advantage ...

Spatial soliton all-optical logic gates

IEEE Photonics Technology Letters, 2006
We demonstrate some basic all-optical (electrically unbiased) logic gates in azobenzene liquid crystalline cells, exploiting their large nonlinearity for light localization and the trans-cis photoisomerization for all-optical external control. Spatial solitons were excited at microwatt power levels at 632.8 nm, whereas gating and switching were ...
