2-Gbit/s Visible Light Modulation Using GaN-Based Photonic Crystal Light-Emitting Diodes without Pre- and Post-Emphasis

Recently, GaN based light-emitting diodes (LEDs) have become a promising candidate for visible light communication (VLC). In this work, we demonstrated 2-Gbit/s data rate transmission using GaN-based LEDs with photonic crystal (PhC) structure.
