Photonic-crystal surface-emitting laser (PCSEL) is a promising technology that can completely revolutionize what lasers ...

In this work, a micro displacement sensor based on a dual micro cavity coupled to a photonic crystal waveguide is proposed. The defects are introduced to create a sharp resonance in the structure ...

In a first for the field, researchers from The Grainger College of Engineering at the University of Illinois Urbana-Champaign ...

Researchers at the University of Illinois have pulled off a laser first: they built a new kind of eye-safe laser that works ...

Scientists have discovered a revolutionary new method for creating quantum states by twisting materials at the M-point, revealing exotic phenomena previously out of reach. This new direction ...

A new silicon material switches from insulator to metal in picoseconds. This breakthrough could speed up future computers.

Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings ...

An international team, led by Donostia International Physics Center (DIPC), has discovered a new way to design novel quantum ...

Abstract: In this paper, we report the impact of lattice-mismatch-induced strain and radial-force-induced strain on the conduction band structures, the acoustic-phonon-limited and ...
