Monitoring liquid dynamics on the chip-scale.

Speaker: Prof. Borislav Hinkov from TU Wien. Institute of Solid State Electronics & Center for Micro- and Nanostructures.
Date: 16/12/2022.
Time: 10:00am.
Lugar: Room B-223. Escuela Técnica Superior de Ingenieros de Telecomunicación UPM.
Monitoring gases and liquids in the mid-IR spectral range is a very sensitive and selective technique for molecule analysis. However, probing dynamical processes in liquids like chemical reactions or conformational changes is often still limited to bulky sensor systems, requiring time consuming offline analytics. This work will present a photonic integration concept, enabling miniaturized liquid sensors with specifically tailored characteristics for dynamical measurements. The combination of samewavelength mid-IR quantum cascade laser and detector (QCLD) devices with novel surface-sensitive mid-IR plasmonic waveguides, unlocks the realization of monolithic lab-on-a-chip sensors for the chemical analysis of liquids. They are further optimized by enhancing the plasmonic sensing section and e.g. increasing its spectral bandwidth or implementing functionalization to address specific molecules. In the final part, new pathways for plasmonic beam guiding along the chip surface are presented. They enable much more complex chip-scale mid-IR photonic integrated circuits (PICs) and networks for applications in advanced liquid spectroscopy and mid-IR free space telecommunication.

Liquid Crystal (LC) technologies are starting to be studied at mm-wave bands in order to develop tunable devices that work properly at those frequency ranges. Because of its birefringence, by applying a low-frequency electric field to a cavity containing nematic LC, its electromagnetic properties can be varied and therefore the device response changes. This varying behavior is related to a continuous change on the electric permittivity, which can be leveraged to vary the resonant frequency or beam of an antenna, or to tune the different elements in a reflectarray antenna, to name a few. Recently, the use of nematic LC as the key phase-shifting element of the upcoming Reconfigurable Intelligent Surfaces (RIS), planar devices able to manipulate electromagnetic propagation, has been proposed, as it is one of the few tunable technologies with moderate cost capable of keeping the pace of the high frequencies (>100GHz) expected in future network generations beyond 5G. Nevertheless, the relatively slow switching times between states, in the order of seconds, is the main weakness of such LC-based devices. However, to be fully implantable in future ultra-reliable low-latency communication networks, improving these times is of utmost importance due to the stringent dynamic requirements of upcoming communication protocols. In this talk, different solutions to overcome this challenge will be discussed.

Solid-state quantum light sources: from semiconductor QDots to 2D crystal QDots.

Our society needs to face huge problems such as climate change and pollution that represent big threats to public health and to our environment, hence the need of designing and fabricating devices that could be able to detect and quantify some of the most representative chemical species related to these issues. In this talk, we are going to talk about how piezoelectric devices, and more specifically Film Bulk Acoustic Resonators (FBARs), could be an interesting technology to fabricate gas sensors intended to detect a wide variety of chemical species under harsh conditions and a brief approach on their design and fabrication techniques.
