A Reconfigurable Optical Logic Gate With up to 25 Logic Functions Based on Polarization Modulation With Direct Detection

open access: yesIEEE Photonics Journal, 2017
We propose and investigate a new scheme to realize optical logic gates using polarization addition with direct detection. Two polarizations of an optical signal are modulated, respectively, by independent binary inputs to represent four different states,

All-optical logic gate operating with single wavelength

open access: yesOptics Express, 2014
We design scalable all-optical logic gates that operate with the same input and output wavelength. We demonstrated the operation by using coupled mode equations, and investigated the impact of input power fluctuations and fabrication errors. We found that a wavelength fluctuation 0.3 times greater than the resonant wavelength width will degrade the ...

Multifunctional logic gates based on resonant transmission at atomic-plasmonic structure

open access: yesScientific Reports, 2022
Regarding the confinement of light at nanoscale dimensions in plasmonic structures, we try to show the impact of hot atomic vapor spectroscopy on a miniaturized scale. In such a combined structure, resonant coupling of the atom to plasmonic mode provides

All-optical switch and logic gates based on all-dielectric hybrid silicon-Ge2Sb2Te5 metamaterials

open access: yes, 2019
We numerically propose an all-dielectric hybrid metamaterial (MM) to realize all-optical switch and logic gates in shortwave infrared (SWIR) band. Such MM consists of one silicon rod and one Ge2Sb2Te5 (GST) rod pair.

Experimental realization of topologically-protected all-optical logic gates based on silicon photonic crystal slabs

open access: yes, 2023
Topological photonics has been developed for more than ten years. It has been proved that the combination of topology and photons is very beneficial to the design of robust optical devices against some disturbances.

Reconfigurable all-optical logic gates based on FWM in semiconductor optical amplifier

open access: yes, 2006
We have demonstrated reconfigurable all optical logic gates based on FWM in single SOA using polarization encoded signals. Six different logic functions can be realized by simply adjusting two polarization controllers in the setup. © 2006 Optical Society
