The recent progress in the development of measurement systems for autonomous recognition had a substantial impact on emerging technology in numerous fields, especially robotics and automotive applications. In particular, time-of-flight (TOF) based light detection and ranging (LiDAR) systems enable to map the surrounding environmental information ov...

The colorimetric sensor-based electronic nose has been demonstrated to discriminate specific gaseous molecules for various applications, including health or environmental monitoring. However, conventional colorimetric sensor systems rely on RGB sensors, which cannot capture the complete spectral response of the system. This limitation can degrade t...

Plasmonic nanostructures allow the manipulation and confinement of optical fields on the sub-wavelength scale. The local field enhancement and environmentally sensitive resonance characteristics provided by these nanostructures are of high importance for biological and chemical sensing. Recently, surface lattice plasmon resonance (SLR) research has...

Surface plasmon resonance (SPR) sensors are based on photon-excited surface charge density oscillations confined at metal-dielectric interfaces, which makes them highly sensitive to biological or chemical molecular bindings to functional metallic surfaces. Metal nanostructures further concentrate surface plasmons into a smaller area than the diffra...

Plasmonic nanoantennas have been extensively explored to boost nonlinear optical processes due to their capabilities to confine optical fields on the nanoscale. In harmonic generation, nanoantenna array architectures are often employed to increase the number of emitters in order to efficiently enhance the harmonic emission. A small laser focus spot...

Surface plasmons, the collective oscillation of electrons, enable the manipulation of optical fields with unprecedented spatial and time resolutions. They are the workhorse of a large set of applications, such as chemical/biological sensors or Raman scattering spectroscopy, to name only a few. In particular, the ultrafast optical response configure...
Conference Paper
The surface plasmons on the metallic nanohole induce nonlinear optical transmission and phase retardation of incident beam. We report that the phase can be precisely controlled by adjusting dislocation between two nanohole arrays.

... As their process can be generally applied to the deposition of any metals, their work opens the door for research into multilayers of combinations of nanoporous metals. Finally, work by Jeong et al. [20] reveals how they create a one-step stencil lithography technique to fabricate 3D surface lattice plasmon resonances in inclined nanostructures. The symmetry-breaking that the inclined structures provide allows for an increase of the polarizability of the created metasurfaces which allows for an increased directionality of the scattered field. ...
... In addition, various analytical techniques for evaluating perovskite light-emitting diodes were introduced. Jeong et al. [20] proposed a plasmonic-amplified third harmonic generator. The authors utilize a plasmonic nanoantenna array to improve the beam stability of position-dependent thirdharmonic yield. ...
... Recently, with the tremendous advance in nanoscale material engineering and manipulation techniques, a new emerging field called atto-nanophysics [15,16] appeared. Bulk samples have been scaled in size to nanometers, providing the probability of studying light-nanostructure interactions. ...
