recommendations! Published in 2020 at "Microwave and Optical Technology Letters"

DOI: 10.1002/mop.32306

Abstract: We demonstrate a higher‐bandwidth and optical power GaN‐based blue light‐emitting diode for visible‐light communication applications. By using a hollow‐runway active area and hollow‐runway current‐confined aperture structure, we obtain an electrical‐to‐optical (E‐O) 3 dB bandwidth (f−3 dB)… read more here.
