The Future of 3-D Printing
Three-dimensional printing technology has created a lot of buzz lately among politicians, engineers and hobbyists alike. But how realistic are the claims being made on its behalf?
Underwater Imaging Gets Clearer
Underwater imaging in natural bodies of water is notoriously difficult due to the large range of particulates that can impede light propagation. However, recent developments in optical technology that build on polarization-based encryption and lidar are leading to incremental advances.
Nonlinear Optics in Crystalline Whispering Gallery Resonators
Christoph Marquardt, Dmitry Strekalov, Josef Fürst, Michael Förtsch and Gerd Leuchs
Whispering gallery resonators made from crystalline materials are compact, stable and highly tunable. These versatile devices can produce light in the classical and quantum domains, showing promise for applications in spectroscopy, metrology and quantum information schemes.
