C-plane yellow–green InGaN micro-light-emitting diodes with 1.55 GHz modulation bandwidth for free-space visible-light communication
Yellow–green InGaN micro-light-emitting diodes (micro-LEDs) are attractive transmitters for visible-light communication, yet high-In-content quantum wells usually impose a trade-off among efficiency, optical power, and modulation speed. Here, we report c-plane single-quantum-well InGaN micro-LEDs emitting near 545 nm t...
