Metalens Array for Complex‐Valued Optical Discrete Fourier Transform
A single‐layer metalens‐array device performs complex‐to‐complex discrete Fourier transforms (DFTs) optically with O(N) digital time complexity. Integrated interferometric phase retrieval and error mitigation scheme enables accurate, compact, and low‐power optical computing. The approach provides a versatile framework for implementing arbitrary complex‐

Mid‐Infrared Intersubband Transitions in p‐Type SiGe Parabolic Quantum Wells
The design, growth, and characterization of hole‐doped Ge‐rich SiGe parabolic quantum wells exhibiting mid‐infrared intersubband transitions are reported. Structural analyses confirm the parabolic compositional profile, while optical spectroscopy supported by tight‐binding simulations demonstrates strong and temperature‐stable absorption up to room ...

Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...

This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...
