PORTLAND, Ore. — Silicon circuits traditionally don't do optics. As an “indirect bandgap” material — one in which the bottom of the conduction band is shifted with respect to the top of the valence ...

Researchers from North Carolina State University have discovered a technique for controlling red light with electric fields, with possible applications in photonics. It involves layers of thin ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) say they have made it easier to manipulate light at the nanoscale. They have developed the first on-chip ...

Professor Kaoru Minoshima from the University of Electro-Communications and NEOARK Corporation have succeeded in prototyping a greatly improved magneto-optic effect (*1) measurement device as part of ...

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent gradient refractive index (GRIN) ...
