(Nanowerk News) Dielectric optical microresonators confine and concentrate light in a tiny circular path due to multiple near total internal reflections at the curved dielectric-air interface, where ...

(Nanowerk News) Transistors in computer chips work electrically, but the data can be transmitted more quickly with light. Researchers have therefore been looking for a way to integrate a laser ...

Colloidal quantum-dots (CQDs) have emerged as promising gain media for lasers, offering low lasing thresholds, compatibility with low-cost solution-based synthesis and processing methods, and tunable ...

Over the past decade, the idea of photonic computing - where electrons are replaced with light in microelectronic circuits - has emerged as a future technology. This promises low-cost, ...

Elastomer microlasers allow biosensing in living systems to study growth. Researchers at the University of Cologne have developed an optics-based method of sensing the mechanical forces at work within ...

Researchers demonstrated that nanowires made from lead halide perovskite are the most efficient nanowire lasers known.. Known for their low cost, simple processing and high efficiency, perovskites are ...
