Radiation and Optics Laboratory

The Radiation and Optics Laboratory , carries out research at the physical level of telecommunications networks, of which the optical fibre infrastructure and the radio frequency channel are components.

The laboratory team is responsible for the design and development of both analogue and high-speed digital microwave electronics for optical and microwave communication equipment, the modelling and simulation of 3D passive microwave structures and the development of antennas up to the terahertz frequency range.

Most of the research equipment was obtained from European projects under the TEMPUS programme and later from the European Union Framework Programmes, as well as from foreign and domestic industrial projects. The laboratory has developed, manufactured and tested microwave and high-speed electronic components for the European projects ESTER, ATLAS and IPHOBAC. The head of the laboratory also participated in the design and construction team for the Microsat and AMSAT P3D artificial satellites.

The Radiation and Optics Laboratory has state-of-the-art radio-frequency measurement equipment for antenna characterisation, spectrum measurements and S-parameter measurements. These include an RF spectrum analyser up to 50GHz, a vector circuit analyser up to 20GHz, a scalar circuit analyser up to 40GHz and various RF sources up to 40GHz. For the measurement of the radiated properties of antennas, the laboratory has a professional measuring station with all associated equipment on the roof of the faculty.

State-of-the-art optical measurement equipment (Fabry-Perot optical spectrum analyser, tunable optical attenuators, optical power meters, optical reflectometers and various optical sources for 1.3um and 1.55um) enables measurements of the optical spectrum of telecommunication wavelengths and measurements of properties and phenomena on optical fibre. The communication equipment allows time-domain measurements with a sampling oscilloscope and measurements of the bit error rate in the telecommunication link.

The laboratory is also a part of the teaching process of the Faculty of Electrical Engineering in Ljubljana, as lectures for courses in the field of optical and radio communications are given at both undergraduate and postgraduate levels, supported by a wide range of interesting, dynamic and instructive laboratory exercises.

In addition to European and government projects, the laboratory is also open to industrial cooperation in the field of optical and radio communications.
