Engineers achieve efficient integration of quantum dot lasers on silicon chiplets
8+ mon, 4+ week ago (160+ words) Lasers that are fabricated directly onto silicon photonic chips offer several advantages over external laser sources, such as greater scalability. Furthermore, photonic chips with these "monolithically" integrated lasers can be commercially viable if they can be manufactured in standard semiconductor…...
Chiral metasurfaces encode two images: One visible, one revealed by polarized light
8+ mon, 4+ week ago (231+ words) by Celia Luterbacher, Ecole Polytechnique Federale de Lausanne edited by Lisa Lock, reviewed by Andrew Zinin By leveraging the concept of chirality, or the difference of a shape from its mirror image, EPFL scientists have engineered an optical metasurface that…...
Defects in single-crystal indium gallium zinc oxide could fix persistent display instability
9+ mon, 6+ day ago (432+ words) edited by Gaby Clark, reviewed by Robert Egan However, IGZO-based devices face long-term stability issues, such as negative bias illumination stress, where prolonged exposure to light and electrical stress shifts the voltage required to activate pixels. These instabilities are believed…...
