CAMBRIDGE, Mass. -- A photonic crystal specially designed to bend light sharply with near-perfect transmission could be the key to further miniaturization of optical computer chips and lasers, according to the scientists at the Massachusetts Institute of Technology who are developing it. The research team simulated a two-dimensional GaAs photonic crystal that acts as a waveguide, steering light around a slightly rounded corner at 100 percent transmission and around a sharp 90° bend at 98 percent efficiency. Within the same volume, the best yield the traditional means of controlling...Read full article
