New integrated device for nanometer-scale sensing

Researchers at Eindhoven University of Technology have developed a new, integrated optical sensor that provides increased resolution in measurements and paves the way for fully integrated and compact optical sensors including ...

Using noise to enhance optical sensing

In conventional sensing methods, noise is always a problem, especially in systems that are meant to detect changes in their environment that are hardly bigger or even smaller than the noise in the system. Encountering this ...

Superman's laser vision a step closer to reality

Superman's ability to shoot laser beams from his eyes has come a step closer to reality, with discoveries made by a research team at the University of St Andrews.

Researchers create fiber optic sensors that dissolve in the body

For the first time, researchers have fabricated sensing elements known as fiber Bragg gratings inside optical fibers designed to dissolve completely inside the body. The bioresorbable fiber Bragg gratings could be used for ...

A levitated nanosphere as an ultra-sensitive sensor

Sensitive sensors must be isolated from their environment as much as possible to avoid disturbances. Scientists at ETH Zurich have now demonstrated how to remove from and add elementary charges to a nanosphere that can be ...

Researchers get better metrics on laser potential of key material

Researchers from North Carolina State University have developed more accurate measurements of how efficiently a polymer called MEH-PPV amplifies light, which should advance efforts to develop a new generation of lasers and ...
