We demonstrate numerically and experimentally a shape optimization method that enables high efficiency metasurfaces while providing direct control of the structure complexity through a Fourier decomposition of the surface gradient.

Ultra-high brightness green Micro-LEDs with 5 μm pixels were achieved using uniform GaN-on-Si epilayers, exceeding 10⁷ cd/m² brightness and enabling high-resolution Micro-LED displays with CMOS circuit integration.

We propose and experimentally demonstrate a new paradigm for parameter-efficient and robust photonic deep learning based on a Neural Cellular Automata architecture.

Remote plasmonic-like enhancement of fluorescence and Raman signals with a > 100 nm silica layer, separating Ag nanoislands from analyte molecules.

3D optical coherence microscopy of vascular networks enables quantitative analysis of flow dynamics and vessel connectivity at capillary resolution.

Metalens with typical chromatic aberrations, when attached to the distal tip of a conventional endoscope, simultaneously encodes different depths into the RGB channels of a camera at the proximal end.

This article provides a comprehensive review of the current status and future outlook for color-conversion display, focusing on the types of color conversion, color conversion materials, patterning process, and performance improvement strategies.

The SRCPT method enables dynamic visualization of drug clearance pathways with high precision, particularly in cases of liver and kidney dysfunction, enhancing diagnosis and treatment outcomes.
