HTTP:: New Crystal Contains Both Light and Vibrations
--------
Guiding light through optical fibers was never something easy to do, and the communication industry has been using photonic crystals â€" specially patterned materials â€" for the job since the early days. In mobile phones, unwanted frequencies are screened out using similar materials, called phononic crystals, which are able to manipulate mechanical vibrations. Now, for the first time, a group of scientists has learned how to combine the two in one, creating a type of crystal that is able to store both light and mechanical vibrations, Nature News reports. The new “optomechanical” innovation was created at the California Institute of Technology (Caltech), by a team of scientists led by expert Oskar Painter. It can control, trap and guide light and vibrations, a trait that could see it being used for constructing more accurate biosensors, creating interfaces for devices on a chip, and also for creating cooling mechanisms for testing quantum limits. The two types of cr!
ystals that were combined for the innovation perform very different tasks in real life, but Painter says that their structures are remarkably similar to each other. “If you make one type of crystal, you almost automatically make the other type,” he explains. This knowledge, the expert reveals, was not put to ...
