Terahertz All‐Dielectric Maxwell Fisheye Lens Waveguide Crossings via Transformation Optics
All‐silicon terahertz waveguide crossings based on Maxwell fisheye lenses are reshaped using transformation optics to interface with planar waveguides while reducing mode mismatch. Realized via subwavelength perforations in a single etching step, 2 × 2 and 3 × 3 crossings achieve broadband transmission with low loss and ultralow crosstalk across 220 ...

Pupil Plane Multiplexing for Vectorial Fourier Ptychography
This study proposes a cost‐effective, modality‐adaptive multichannel microscopy framework using pupil‐plane multiplexing. A custom pupil aperture at the Fourier plane encodes channel‐specific transfer functions with spectral or polarization filters, and model‐based reconstruction with channel‐dependent priors decodes them.

Generation of Optical Quasiparticles with Spin–Orbit Conversion in a Single Q‐Plate
Spin‐Orbit conversion approach with a q‐plate for generating optical quasiparticles. ABSTRACT In this work, we detail a novel approach which can be used for the generation of optical quasiparticles. This process leverages both spin‐orbit conversion control with wavelength de‐tuning in a commercially available q‐plate.
