Free Space Optical communications are steadily emerging, due to the numerous and various benefits that they offer. Although FSO systems are based on a cheap, safe and efficient technology, there are many degrading effects that should be taken into account. In particular, long and fast links suffer from many existing effects, acting cumulatively, resulting in a not negligible deterioration of both performance and availability, as their length or bit rate increases. And that is because of the FSO pulse propagation through dispersive atmospheric channels, while short timed pulses are prone to be misdetected in adjacent time slots at the receiver, leading to disturbances in the bit stream, consequently. This work includes the estimation of FSO link performance, focusing on both the group velocity dispersion and the time jitter effects, calculated in terms of both probability of fade and outage probability, using closed form mathematical expressions. Then, interesting numerical results and conclusions are presented for typical FSO links' parameters.

Advantages of optical links for data transmission are doubtless. Different types of optical interconnects for inter/intra chip links are under development. Electro-optical modulators (EOMs) are one of key elements of optical links. Transmission-type EOM for chip-to-chip optical interconnection is analysed by the method of single expression. Transmission properties of Fabry-Perot resonant type modulator consisting of electro-optical material embedded between Si/SiO2 distributed Bragg reflectors (DBRs) are analysed. From four possible types of DBRs the suitable structure has been chosen. Two semitransparent conducting electrodes for applying electrical signal to electro-optical material are parts of the nano-layered structure and are included in the electromagnetic model. As an external light source, a conventional laser diode of wavelength 1.55 $mu m$ is taken. Efficiency of optical wave intensity modulation is analysed by means of influence of electro-optical material's permittivity change (under applied voltage) on resonator's maximal transmission peak shift. For the electro-optical material LiNbO3 of thickness about 1 mm the suitable resonance peak shift is obtained.

In the course of the ongoing process of defining the future communication standard of 6G, one of the main conceptions is that in future the tasks of communication and sensing will be performed in parallel, utilizing the same waveforms and the same hardware, thus forming a so-called Integrated Sensing and Communication (ISAC) system. In this work, we propose the concept of an ISAC system based solely on visible light that performs the task of sensing the rotational position of a cylinder mounted on a servomotor with an average absolute deviation of ~!1.2° and the task of forwarding the commands to reach a defined rotational position. The feasibility of the implemented ISAC system is verified by experimental results that demonstrate the applicability of such a visible light based ISAC systems in the era of $6mathbf{G}$. Furthermore, we show a simple and effective method to compensate the impacts of additional ambient light on the operation performance.

The recent increasing requirements for high speed and robust wireless communication links have given rise to the development of THz wireless communication systems (0.3-10 THz), as a very promising alternative to their MMW and FSO counterparts. However, the performance of THz wireless systems is subject to free space path loss, signal attenuation due to humid air, atmospheric turbulence and pointing errors between transmitter and receiver terminals. Thus, in this work we first introduce the stochastic impact of generalized PEs with nonzero boresight in the THz area, while atmospheric turbulence is modeled through the suitable gamma gamma distribution. Considering also the deterministic impact of free space path loss and signal attenuation, an outage probability analysis is performed for a typical line of sight THz link. In this context, novel closed form expressions are derived. Their analytical results demonstrate the joint influence of these effects on THz signal transmissions, while simulation results validate the accuracy of our analysis.

A new software tool, called AWG-Channel-Spacing, is developed to calculate accurate channel spacing of an arrayed waveguide gratings (AWG) optical multiplexer/demultiplexer. This tool has been developed with the application framework QT in the programming language C++. The tool was evaluated with a design of 20-channel 200 GHz AWG. The achieved simulated transmission characteristics prove the correct functionality of the tool.

Machine learning is one of key-enablers in case of novel usage scenarios and adaptive behavior within next generation mobile networks. In this paper, it is examined how model-driven approach can be adopted to automatize machine learning tasks aiming mobile network data analysis. The framework is evaluated on classification task for purpose of base station anomaly detection relying on Neo4j graph database. According to the experiments performed on publicly available dataset, such approach shows promising results when it comes to both classification performance and reducing the time required for operations related to data import and model training.

The field of applications for ultra-wideband (UWB) radar has been growing in recent years. One interesting use-case is life presence detection, which is finding living bodies - human or animal - in an otherwise static environment. An example is the localization of humans under debris (e.g. after earthquakes). But also, the automotive sector has found use-cases for UWB radars: monitoring of the driver's vital functions or reminding the driver of children or animals left inside, when the user locks the car and walks away. In particular, it is quite a challenge to detect infants in cars within a short period of time. Compared to adults not a lot of measurement data is available for infants and there are also no appropriate models for numerical simulation. This paper presents the development of such a model including results from simulations that make use of the model.

Performance of linear avalanche photodiode-based balanced homodyne receiver (APD BHD) is examined and compared to reference BHD based on PIN photodiodes, in terms of common mode rejection ratio (CMRR), quantum-to-classical noise clearance (QCNR) and sensitivity in coherent reception of quadrature phase shift keying (QPSK) modulation format. NIST randomness validation was performed on sampled data for quantum random number generator (QRNG). Achieved CMRR values were 50 dB and 30 dB at 100 MHz and 1 GHz, respectively. QCNR of 20 dB at low input power of −20 dBm was demonstrated. Optical sensitivity of APD BHD coherent receiver compared to its PIN BHD counterpart can be improved by 3 dB at low local oscillator (LO) powers, whereas for high LO powers the sensitivity of APD BHD approaches the values for PIN BHD.

In this paper we present various educational activities with Photonics Explorer, an educational kit developed by the photonics research team B - PHOT at VUB (Vrije Universiteit Brussel) for students at secondary schools. The concept is a ‘lab-in-a-box’ that enables students of the 2nd and 3rd grade to do photonics experiments themselves at school with lasers, LEDs, lenses, optical fibers, and other high-tech components. Even though, the kit was developed for the secondary schools, we use experiments from the kit also for some other teaching activities such as lectures at the university, photonics workshops for teachers and children at primary/secondary schools or for events such as children's/youth's university or the night of sciences. In the frame of Austrian based project Phorsch! we have organized most of these activities which will be presented here.
