Abstract :
An 8 × 8 array of AllnGaN micro-LEDs is bump-bonded to a standard 0.35 μm CMOS driver chip. Each pixel can be independently pulsed at a rate of 200 MHz with pulsewidths down to 300 ps FWHM at optical power levels of 0.5 pJ/ns at 370 nm. Circuit techniques to minimize pulsewidths are demonstrated. Applications include chip-to-chip communications and lab-on-chip devices.
