A nanoscale optical device has been developed that allows independent control over the intensity and phase of light. By applying voltage, this innovative device can freely manipulate the phase and ...

A method for configuring light-trapping devices promises better optical nanodevices by amplifying light and enhancing the emission efficiency of luminescent nanomaterials — without the need for ...

For example, by adding or dropping a particular color, or wavelength, of light traveling in an optical fiber, scientists can control the amount of information carried by the fiber. By altering the ...
