Plasmonic and Photonic Modes in Colloidal CuS Nanocrystals

Advanced Optical Materials, EarlyView.
Copper sulfide in the covellite phase (CuS) can exhibit exceptional optoelectronic properties with plasmonic and photonic absorption in its monolithic nanomaterial form. In this work, the phenomenon of near‐infrared (NIR) to visible electromagnetic field localization in ultrathin crystalline quasi‐2D CuS nanocrystals is demonstrated by mapping ...

Predictive Design to Determine Optimal Absorber Placement in Colloidal Photonic Crystals

Advanced Optical Materials, EarlyView.
The inclusion of absorbing material is known to increase color saturation in photonic crystals. Predictive design based on mathematical structure optimization is used to identify optimal designs for the absorber amount and position within a photonic colloidal crystal and experimentally realized. This strategy shows that the placement of the absorber at

Unidirectional Focusing of Light Using Structured Diffractive Surfaces

Advanced Optical Materials, EarlyView.
This study presents a reciprocal diffractive unidirectional focusing design based on linear and isotropic layers. A set of cascaded diffractive layers is designed using deep learning to achieve efficient forward light focusing while suppressing backward propagation across various illumination angles.

Multiple Incoherent Deconvolutions for Improving the Image Resolution of Diffraction‐Limited Imaging Systems

Advanced Photonics Research, EarlyView.
Multiple incoherent nonlinear deconvolutions (MIND) has extended dimension for optimization that provides a better solution than Wiener deconvolution and nonlinear reconstruction. MIND minimizes deconvolution noise by averaging over multiple deconvolutions each with different system aperture that effectively enhances the resolution.

Analysis of Band Effects in One‐Dimensional Periodic Lattices Using an Enhanced Homogenization Method

Advanced Photonics Research, EarlyView.
An enhanced homogenization method for periodic lattices, applicable to any asymmetrical multipart structures, is proposed. This method simplifies intricate gratings into slab waveguides, predicts guided‐mode resonances and bound states in the continuum, without relying on numerical methods.
