Title: Engineering the Quantum Era: Breaking Spectral Barriers for Photonics

Abstract: Nature offers us a full assortment of atoms, but nanoengineering is required to put them together in an elegant way to realize functional structures not found in nature. A particular rich playground for nanotechnology is the so-called III-V semiconductors, made of atoms from columns III and V of the periodic table, and constituting compounds with many useful optical and electronic properties in their own right.  Guided by highly accurate simulations of the electronic structure, modern semiconductor optoelectronic devices are literally made atom by atom using advanced growth technology such as molecular beam epitaxy and metal organic chemical vapor deposition to combine these materials in ways to give them new proprieties that neither material has on its own.  Modern mastery of materials growth and characterization with the help of such techniques allows high-power and highly efficient functional devices to be made, such as those that convert electrical energy into coherent light or detect light of any wavelength and convert it into an electrical signal. This talk will present the latest world-class research breakthroughs that have brought quantum engineering to an unprecedented level, creating light detectors and emitters over an extremely wide spectral range from 0.2 to 300 microns.

Title: Advanced Optical Communications and Networking

Abstract: In a short introduction, the guiding properties of optical fibers are first recalled in a user-oriented presentation including multi and single mode operations. Attenuation mechanisms, group velocity dispersion (GVD), polarization mode dispersion (PMD) and non-linear propagation are presented, as well as their system impairments. The principles and the performances of optoelectronics devices, semiconductor laser (SCL), photo detector and optical modulator are shortly reviewed, including optical amplifier (OA) technologies and associated noise generation. The direct detection (DD) and optically pre-amplified systems are presented as well as and their use in the different implementations of fiber to the home (FTTH) access networks. Wavelength division multiplexing (WDM) and the color management will be addressed and compared to time division multiplexing (ETDM). Its implementations as coarse wavelength division multiplexing (CWDM), for access networks applications, and dense wavelength division multiplexing (DWDM), for long haul and data com applications. For long haul and high bit rate system, the coherent optical detection, allows the optical phase preservation, and therefore to use digital communications techniques such as quadrature amplitude modulation (QAM), forward error coding (FEC), dispersion impairments corrections and orthogonal frequency division multiplexing (OFDM). The today system performances, allowing reaching the Shannon channel capacity are presented, the non-linear noise generation and accumulation being the major impairment. In addition to the polarization diversity, space division multiplexing (SDM) and mode-division multiplexing (MDM) associated with multi-input multi-output (MIMO) technique in multi-core fiber (MCF) and in few-mode fibers (FMF) are finally discussed.

Title: 5G Standardization and Deployment: Focus on 5GNR

Abstract: The proposed talk will introduce the three-pillar approach standardized in ITU for IMT-2020 and will discuss the performance requirements for eMBB (enhanced mobile broadband), URLLC (Ultra Reliable Low Latency Communications) and mMTC (Massive Machine Type Communications). Their interaction with 5G Air Interface technologies standardized by 3GPP such as 5GNR (5G New Radio); mmWave transmission systems and Massive MIMO will be discussed. Core network architecture for the wide variety of applications mentioned above and the flexibility advantages of the introduction of SDN/NFV (mainly standardized by ETSI) will be detailed.

Title: Photoconductive Antenna: A radiation source for the Terahertz Band

Abstract: The characteristics of the Terahertz (THz) frequencies endow them suitable for the different applications related to imaging, security, communication, biomedical, pharmaceutical, spectroscopy and many more. However, availability of efficient sources and detectors remained as a hindrance in harnessing the full potential of Terahertz band. Recent advancements in the field of nanotechnology, semiconductors and laser technology have fuelled substantial research activities in the Terahertz band. Photoconductive Antennas (PCA) are among the most popular sources of THz radiation because of their simplicity, reliability, cost and efficiency. Such antennas can be designed to generate pulsed or continuous-wave Terahertz radiation. Continuous waves are generated through photo-mixing of two continuous wave laser beams on a photoconductive antenna configuration. Such antennas are referred to as Photomixing antenna (PMA). Many studies have been performed over last decade on these antennas to increase their efficiency to make them more suitable for different applications. This talk presents analytical models developed for the pulsed PCA and continuous wave PMA. It also introduces a novel technique to enhance the radiated power from a photoconductive antenna. Graphene, due to its interesting and desired physical and electrical properties, has several potential applications over a wide range of frequencies, especially in the antenna technology. This talk also introduces and discusses Graphene and its application to antennas at the THz band with a few basic results.

Title: Quantum Communication, the next generation of optical communication

Abstract: To date, information is protected by the use of classical algorithms however these techniques are based on the complexity of a mathematical construct. With the progression of powerful resources, some of these mathematical constructs can be broken through brute force attacks. With the shift towards the development of a quantum computer all current conventional encryption technique will eventually be rendered obsolete. Quantum Communication is an emerging technology and an alternative method of ensuring the security of information with great commercial potential. It addresses the challenges confronting conventional encryption approaches, by providing a provably secure cryptographic building block for remote parties to share cryptographic keys. Quantum Communication has the potential to replace or augment existing conventional technologies for secure transmission of encryption keys. Quantum key distribution (QKD) is probably the most paradigmatically implementable technology in the branch of quantum information science. It is based on the idea of point to point transfer of information and is achieved by encoding quantum carriers (qubits). Over the last few decades, several quantum communication links have been established over various distances dependent on the medium of the quantum channel. The demonstration of this technology has been successfully implemented in fiber and free-space and via satellite. Quantum communication, although progressing drastically in the last few years, still has its challenges to overcome to reach a probable end user hybrid quantum network. Quantum information science comprises of three fields, quantum communication, quantum computing and machine learning. Machine learning is a state of the art technique for making predictions and can be applied to quantum communication to optimize the key distribution process especially for free-space quantum links. Here we focus on the advancement of quantum communication and the integration of machine learning in communication systems.
