Abstract The integration of artificial intelligence (AI) systems in the daily life greatly increases amount data generated and processed. In addition to large computational power required, hardware needs be compact energy efficient. One promising approach fulfill those requirements is phase-change material based photonic neuromorphic computing that enables in-memory computation a high degree pa...

A broadband silicon four-mode (de)multiplexer [(De)MUX] is proposed and experimentally demonstrated based on subwavelength gratings (SWGs)-assisted triple-waveguide couplers (TWCs), which can (de)multiplex TE 0 , xmlns:xlink="http://www.w3.org/1999/xlink">1 xmlns:xlink="http://www.w3.org/1...

This paper describes researches concerning the use of Wavelength-Division Multiplexing (WDM) techniques over Polymer Optical Fibres (POFs) links for Residential Networks applications. It is reported the development of a 2-channel WDM Multiplexer/Demultiplexer (MUX/DEMUX) device based on a commercially available dichroic beam-splitter operating in the visible spectra. It describes the use of the...

The optimization of multiplexing (MUX) and demultiplexing (DMUX) 3-dB filter bandwidths for the optical differential quadrature phase shift key (DQPSK) combined with the return-to-zero (RZ) and carrier-suppressed returnto-zero (CS-RZ) is performed. The study of different optical signals in the 40 Gb/s dense wavelength division multiplexing (DWDM) system, with high spectral efficiency, is shown ...

We investigate the possibility to multiplexing (Mux) and demultiplexing (de-Mux) numerically digital holograms (DHs) with the aim of optimizing their storage and/or transmission process. The DHs are multiplexed and demultiplexed thanks to the unique property of the digital holography to numerically manage the complex wavefields. We show that it is possible to retrieve correctly quantitative inf...

Stochastic computing (SC) is a low-cost computational paradigm that has promising applications in digital filter design, image processing, and neural networks. Fundamental to these the weighted addition operation, which most often implemented by multiplexer (mux) tree. Mux-based adders have very low area but typically require long bitstreams reach practical accuracy thresholds when number of su...

Recently testing of Quantum-dot Cellular Automata (QCA) Circuits has attracted a lot of attention. In this paper, QCA is investigated for testable implementations of reversible logic.

This paper is focused on applying a polarization multiplex to passive optical networks double their transmission bandwidth without significant changes in the distribution network. Although multiplexes are already employed for high-speed transport with digital signal processing and coherent detection, we propose system that could be used existing older using dynamic controller combination wavele...
