Systematic Evaluation of Preprocessing Techniques for Accurate Image Registration in Digital Pathology
Image registration refers to the process of spatially aligning two or more images by mapping them into a common coordinate system, so that corresponding anatomical or tissue structures are matched across...
PublikationenDenoising and Baseline Correction of Low-Scan FTIR Spectra: A Benchmark of Deep Learning Models Against Traditional Signal Processing
High-quality Fourier Transform Infrared (FTIR) imaging usually needs extensive signal averaging to reduce noise and drift which severely limits clinical speed. Deep learning can accelerate imaging by reconstructing...
PublikationenHigh-definition 3D suspended Archimedean spiral with broadband, spatially extended, and single-handed optical chirality enhancement in Vis-NIR range
3D plasmonic structures can provide giant optical chirality (C) in the near field, enabling strong interactions with enantiomers for chiral sensing applications. However, these structures face several...
PublikationenPhase Matched Plasmonic Transmission Lines for Cascaded Second-Harmonic Generation as a Pathway to Nonlinear Logic Circuits
In nonlinear nanophotonics, cascaded second-harmonic generation (SHG) in pure plasmonic waveguides for sequential signal transformation and complex on-chip functionality remains a long-standing challenge....
PublikationenSynthetic Spatiotemporal Plasmonic Vortices On Chip
Spatiotemporal vortices are polychromatic modes that intertwine orbital angular momentum (OAM) in space and time. Here we introduce a new class of such vortices, spatiotemporal plasmonic vortices (STPVs),...
PublikationenMeasuring coherent dynamics of a superconducting qubit in an open waveguide
We measured the relaxation and decoherence rates of a superconducting transmon qubit in a resonator-free setting. In our experiments, the qubit is coupled to an open coplanar waveguide such that the transmission...
PublikationenOn-chip twisted hollow-core light cages: enhancing planar photonics with 3D nanoprinting
Twisted optical fibers are a promising platform for manipulating circularly polarized light and orbital angular momentum beams for applications such as nonlinear frequency conversion, optical communication,...
PublikationenStimulated Emission from 2D CdSe/CdS Nanoplatelets Integrated in a Liquid-Core Fiber
Colloidal nanocrystals are unique optical gain materials due to their high intrinsic absorption, excellent quantum yield, and tunable emission. However, integration of colloidal nanocrystal solutions into...
PublikationenEnhancing entangled two-photon absorption of Nile Red via temperature-controlled SPDC
Entangled two-photon absorption can enable a linear scaling of fluorescence emission with the excitation power. In comparison to classical two-photon absorption with a quadratic scaling, this can allow...
