Nanoscale optical device enables independent control of light intensity and phase using electricity
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 ...
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 ...
White Light Emitting Diodes (LED) replace HID lamps in street lighting system to include a dimming feature. A microcontroller of 8051 family is used to control the intensity by developing pulse width ...
Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...
A project at Lawrence Livermore National Laboratory (LLNL) and Sandia National Laboratories has identified a new way to optimize the quality of 3D-printed thermoplastics. Described in Science, the ...
