McKendry, David Massoubre, Shuailong Zhang, Bruce R. Rae, Richard P. Green, Erdan Gu, Robert K. Henderson, A. E. Kelly, and Martin D. Dawson, Fellow, IEEE rescindWe report the high-frequency conversion of person pixels in 8 8 militarys of III-nitride-based micro-pixellated high spirits-emitting diodes, where the pixels within the array range from 14 to 84 m in diameter. The peak emission wavelengths of the devices ar 370, 405, 450 and 520 nm, respectively. Smaller welkin micro-LED pixels generally exhi point higher flexion bandwidths than their larger area counterparts, which is attributed to their ability to be driven at higher actual densities. The highest optical dB modulation bandwidths from these devices are shown to be in excess of 400 MHz, which, to our knowledge, are the highest bandwidths to that degree reported for GaN LEDs. These devices are also integrated with a complementary metal-oxide-semiconductor (CMOS) driver array snowflake, allowing for simple computer control of individual micro-LED pixels.

The bandwidth of the integrated micro-LED/CMOS pixels is shown to be up to 185 MHz; data contagious disease at bit rates up to 512 Mbit/s is demo development on-off keying non return-to-zero modulation with a bit-error ratio of less than , using a 450 nm-emitting 24 m diameter CMOS-controlled micro-LED. As the CMOS chip allows for up to 16 independent data inputs, this device demonstrates the pote ncy for multi-Gigabit/s latitude data trans! mission using CMOS-controlled micro-LEDs. major power Termscomplementary metal-oxide-semiconductor (CMOS), GaN, micro-light-emitting diodes (micro-LEDs), modulation, visible light communications (VLC).
