A new technique developed by MIT researchers reveals the inner details of photonic crystals, synthetic materials whose exotic optical properties are the subject of widespread research.
Ultrashort bursts of electrons have several important applications in scientific imaging, but producing them has typically required a costly, power-hungry apparatus about the size of a car.
Lasers + anti-lasers: Marriage opens door to development of single device with exceptional range of optical capabilities
Bringing opposing forces together in one place is as challenging as you would imagine it to be, but researchers in the field of optical science have done just that.
An electric current will not only heat a hybrid metamaterial, but will also trigger it to change state and fade into the background like a chameleon in what may be the proof-of-concept of the first controllable metamaterial ...
A team of UCF researchers has produced the most efficient quantum cascade laser ever designed - and done it in a way that makes the lasers easier to manufacture.
