Principles for single-pixel terahertz imaging based on the engineering of illuminating and collecting nonparaxial diffractive optics
Sergej Orlov, Rusnė Ivaškevičiūtė-Povilauskienė, Karolis Mundrys +7
The art of light engineering unveils a world of possibilities through the meticulous manipulation of photonic properties such as intensity, phase, and polarization. The precise con…
Coloured Digital Terahertz Holography Within 1.39-4.25 THz range
Rusne Ivaskeviciute-Povilauskiene, Linas Minkevicius, Ignas Grigelionis +5
Terahertz coloured digital holography ranging from 1.39 THz up to 4.25 THz is demonstrated. It is shown that it can be applied for the investigation of low-absorbing objects, and i…
Advantages of optical modulation in terahertz imaging for study of graphene layers
Rusnė Ivaškevičiūtė-Povilauskienė, Alesia Paddubskaya, Dalius Seliuta +7
It was demonstrated that optical modulation together with simultaneous terahertz (THz) imaging application enables an increase in contrast by an order of magnitude illustrating hen…
Influence of field effects on the performance of InGaAs-based terahertz radiation detectors
Linas Minkevičius, Vincas Tamošiūnas, Martynas Kojelis +6
A detailed electrical characterization of high-performance bow-tie InGaAs based terahertz detectors is presented along with simulation results. The local surface potential and tunn…
