High Modulation Bandwidth of Semipolar (11-22) InGaN/GaN LEDs with Long Wavelength Emission.

Visible light communication requires III-nitride LEDs with a high modulation bandwidth but have c-plane limitations. General illumination requires green/yellow III-nitride LEDs with high optical efficiency that are difficult to achieve on c-plane substrates. Micro-LEDs with a low efficiency are used to obtain a high modulation bandwidth.
