SCALING OF OPTICAL LOGIC DEVICES AND ARRAYS

Le Journal de Physique Colloques, 1988
The use of ion-beam-assisted etching to form ~ 1.5-µm diameter waveguiding "posts", or microresonators, in a GaAs/AlAs Fabry-Perot structure grown entirely by molecular beam epitaxy has reduced the device cross-sectional areas, energy requirements and recovery times all by more than an order of magnitude1.

Time-Domain Separation of Optical Properties From Structural Transitions in Resonantly Bonded Materials [PDF]

, 2015
The extreme electro-optical contrast between crystalline and amorphous states in phase change materials is routinely exploited in optical data storage and future applications include universal memories, flexible displays, reconfigurable optical circuits,

Flexible Crystal Heterojunctions of Low-Dimensional Organic Metal Halides Enabling Color-Tunable Space-Resolved Optical Waveguides

Research, 2023
Molecular luminescent materials with optical waveguide have wide application prospects in light-emitting diodes, sensors, and logic gates. However, the majority of traditional optical waveguide systems are based on brittle molecular crystals, which ...

Logical operations with Localized Structures [PDF]

, 2012
We show how to exploit excitable regimes mediated by localized structures (LS) to perform AND, OR, and NOT logical operations providing full logical functionality. Our scheme is general and can be implemented in any physical system displaying LS.

Single Photon Source Using Laser Pulses and Two-Photon Absorption [PDF]

, 2006
We have previously shown that two-photon absorption (TPA) and the quantum Zeno effect can be used to make deterministic quantum logic devices from an otherwise linear optical system.

Energy-efficient domain wall motion governed by the interplay of helicity-dependent optical effect and spin-orbit torque [PDF]

, 2019
Spin-orbit torque provides a powerful means of manipulating domain walls along magnetic wires. However, the current density required for domain wall motion is still too high to realize low power devices.

Logic functions based on optical bias controlled SiC tandem devices [PDF]

physica status solidi c, 2014
AbstractThe purpose of this paper is the design of an optoelectronic circuit based on a‐SiC technology, able to act simultaneously as a 4‐bit binary encoder or a binary decoder in a 4‐to‐16 line configurations and show multiplexer‐based logical functions.

Experimental realization of a CMOS-compatible optical directed priority encoder using cascaded micro-ring resonators

Nanophotonics, 2018
In this paper, we propose and experimentally demonstrate an integrated optical device that can implement the logical function of priority encoding from a 4-bit electrical signal to a 2-bit optical signal.
