Abstract:

Last decades brought a considerable development of technologies based on ordered systems. Starting with semiconductor physics and photovoltaics, technologies soon evolved towards the utilisation on large scale of thin films and of surface / interface properties. Example go nowadays from data storage and readout (electrostatic or magnetic memories, giant magnetoresistance) to catalysis, gas sensors or photocatalysis (surface phenomena), and towards interfaces with biological matter (biosensors, templates for tissue reconstruction, interfaces between biological electrical signals and microelectronics). In Romania, crystal growth is performed since half a century; nevertheless, during the last years these activities fade out and need to be seriously reinforced, especially with the advent of new laser and detector technologies required by the Extreme Light Infrastructure facilities. Also, surface science started to be developped seriously only during the last decade, together with techniques involving self-organized nanoparticles, nanoparticle production etc. The main goal of this Project is to gather the relevant experience from the five partners, namely the experience in crystal growth from the University of Timișoara, with the surface science, nanoparticle and nanowire technologies developped by NI of Materials Physics, the cryogenic and ultrahigh vacuum techniques provided by the NI for Cryogenic and Isotopic Technologie, and the experience in ordered 2D systems (graphene and the like) owned by the NI for Microtechnologies (IMT). This common agenda will result in a coherent fostering of technologies relying on ordered systems of variable dimensionalities: 0D i.e. clusters or nanoparticles, including quantum dots; 1D i.e. free and supported nanowires and nanofibers; 2D: surfaces, interfaces and graphene-like systems; and 3D crystals of actual technological interest, together with setting up new ultrahigh vacuum, surface science and electron spectroscopy techniques.

Technological transfer to increase the quality and security level of holographic labels Call name: P 2 - SP 2.1 - Proiect de transfer la operatorul economic

Abstract:

In this context, the economic agent, Optoelectronica 2001, through the TSCEH project, decided to increase the security level and the quality of their holographic labels, following a strategy based on technological transfer:

1. from the Microtechnology Institute of Bucharest, to include a new security element in the shape of submicrometric structures

2. from Politehnica University of Bucharest, to improve the optical and morphological properties, by iterative optimization of the characterization processes.

The results will be at TRL6:

obtaining a prototype of holographic label with a new security element, of submicrometric structure type (EHS), fabricated using a modified technology, demonstrated in industrial environment.

OPTOEL produces holographic labels using a technology based on a mask obtained with modulated laser beam. These labels contain many security elements as optical effects. The challenge of this project is to find the technological solutions to include in a free zone from this mask of the submicrometric structures made starting from electron beam lithography.

The innovative character of the TSCEH project is proven by:

1. Changes in the technological steps by finding the optimal solution to include the submicrometric structures

2. Improving the optical and morphological properties by setting the optimal values of the parameters involved in the technological processes.

Abstract:

The goal of the SelectX project is to propose a technologic alternative for the hardware implementation of the artificial neural networks in a flexible and energy efficient manner. The biological neural networks, although slow, have an extraordinary performance for certain types of problems, such as visual recognition, natural language processing, etc.

Trying to mimic in a rudimentary way the organization of biological neural networks, the artificial neural networks are becoming widely used in software (Google Machine Intelligence, Facebook Artificial Intelligence Research). Unfortunately, this approach is power intensive (kW of power) and requires a large amount of computational resources (hundreds of traditional multi-core processors).

The memristor is a passive two-terminal device which has an analog resistance, tunable through voltage pulses. This makes it attractive for use as artificial synapse. A hybrid system made of dense memristor synaptic matrices (“crossbars”), fabricated directly on the surface of a transistor (CMOS) neural chip could implement very complex artificial neural circuits.

A fundamental problem with the memristor passive matrix matrices is the existence of leakage currents which prevents the correct reading of the value of the memristor resistance and, consequently, the produces the incorrect operation of the circuit. These leakage currents can be reduced to insignificant values if the matrix contains components with high non-linearity.

Abstract:

This project aims to validate a novel concept into a potential free space optical communication (FSOC) technology

that allows to dramatically increase the volume of the transmitted information over a free space link by modulating

a particular class of laser beam configurations called optical vortices (OV). These appear as a result of reshaping

a laser Gaussian beam by a computer generated hologram and they carry orbital angular momentum an additional photon's

degree of freedom used for data encoding. Besides the high volume of information, this concept provides an intrinsic

secure character of the free space optical link without relying to the mathematical encryption of data. For accomplishing

this goal a consortium formed by National Institute for R&D in Microtechnologies (coordinator), SC Optoelectronica SA and

Politehnica University Bucharest will build and test a functional model of an optical vortices FSOC system, addressing

the specific topics realated to its realization: design and fabrication of efficient computer generated holograms,

innovative optical design and high performance electronic modules. The possible use of this potential FSOC technology

are in terrestrial and space applications requiring high volume data transmissions.
