Generation of Optical Chirality Patterns with Plane Waves, Evanescent Waves and Surface Plasmon Waves
Jiwei Zhang, Shiang-Yu Huang, Zhan-Hong Lin +1
We systematically investigate the generation of optical chirality patterns by applying the superposition of two waves in three scenarios, namely plane waves in free space, evanesce…
Chiral Structured Illumination Microscopy
Shiang-Yu Huang, Jiwei Zhang, Christian Karras +3
We propose a chiral imaging modality based on optical chirality engineering, fluorescence-detected circular dichroism and structured illumination microscopy. In this method, the op…
Driving plasmonic nanoantennas at perfect impedance matching using generalized coherent perfect absorption
Philipp Grimm, Gary Razinskas, Jer-Shing Huang +1
Coherent perfect absorption (CPA) describes the absence of all outgoing modes from a lossy resonator, driven by lossless incoming modes. Here, we show that for nanoresonators that…
Design and Characterization of Plasmonic Doppler Grating for Azimuthal Angle-resolved Surface Plasmon Resonances
Kel-Meng See, Fan-Cheng Lin, Jer-Shing Huang
We present two-dimensional plasmonic Doppler grating (PDG) for broadband azimuthal angle-resolved nanophotonic applications. The PDG consists of a set of non-concentric circular ri…
Designable spectrometer-free index sensing using plasmonic Doppler gratings
Fan-Cheng Lin, Kel-Meng See, You-Xin Huang +4
Typical nanoparticle-based plasmonic index sensors detect the spectral shift of localized surface plasmon resonance (LSPR) upon the change of environmental index. Therefore, they r…
Symmetry-controlled second-harmonic generation in a plasmonic waveguide
Tzu-Yu Chen, Julian Obermeier, Thorsten Schumacher +4
A new concept for second-harmonic generation (SHG) in an optical nanocircuit is proposed. We demonstrate both theoretically and experimentally that the symmetry of an optical mode…
