3D Construction Ahead

One of the interesting features of Photonics West is that it covers the full spectrum, from academic research to industrial research to new products in the commercial exhibits. This range of interrelated ideas was on show in 3D fabrication. At one extreme, the latest research in scanning multi-spot three-photon patterning showed 3D structures 100μm thick with 50nm features. Researchers als... » read more

Quantum Cryptography: A Magic Bullet For The IoT?

Quantum cryptography (QC for this discussion) theory—and it is still just theory—is potentially a very powerful security process that could be implemented for the dissemination of information over communications channels, using the principles of quantum mechanics. This is particularly intriguing because it is impossible to measure a photon, the fundamental element in the creation of QC secu... » read more
