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 ...

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 ...

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 ...
