Research objectives

The laboratory's objective is to develop and improve far- (THz) and mid-infrared devices, components and systems, to study their physical properties and develop their practical applications in industry, medicine and environmental protection. It also aims to develop advanced terahertz photonics technologies for imaging, spectroscopy and sensor systems.

Main research areas:

1. Semiconductor materials and devices

Investigation of physical properties of wide-gap (GaN, GaO) semiconductors, AlGaAs/GaAs, AlGaN/GaN, AlGaO/GaO heterojunctions, quantum wells, superlattices and other nanostructures for application in THz photonics and optoelectronic devices.

2. Compact THz detectors, emitters and other components

Research and Development of room-temperature THz detectors and sources, optical and photonics components for application in material science, environmental and atmospheric research, spectroscopic imaging, safety, communication and medical systems.

3. 1D and 2D materials, metasurfaces, and metamaterials

Investigation of the physical properties of 2D materials, graphene, carbon nanotubes, composites and nanostructures, metaatoms, metasurfaces and metamaterials using broadband THz/IR spectroscopy, involving as well applied studies of the surface plasmon/phonon polaritons and other quasiparticles.

4. Engineering of integrated THz photonics systems

Integration of THz detectors, sources, filters, lenses, splitters, polarizers and other elements into chips and hybrid systems using structured light engineering.
