A 520-nm Green GaN LED with High Bandwidth and Low Current Density for Gigabits OFDM Data Communication

摘要

We develop 520-nm green GaN LEDs with a 340-MHz E-O bandwidth. For the first time, an OFDM signal modulates the green LED, which data rate achieves 2.16 Gb/s at a low current density 679 A/cm2.
