Monolithic White and Multi-Color Lasers Tunable in Full Visible Spectrum
Semiconductor lasers able to emit over the full visible color spectrum have a wide range of practical applications such as solid-state lighting, full-color displays, visible color communications, and multi-color fluorescence sensing. To the human eye, light with a mixture of four monochromatic lasers is visually equivalent to a white illuminant. Current...

High Efficiency Power Transistor Gate Drive
IntroductionGate-drive technology is traditionally an open-loop passive method that has no real-time control of a semiconductor power device’s switching speed, overshoot, and switching power losses. The technology is unreliable and cannot be optimized over different operating voltages and current conditions. It suffers high transient overshoots...
