2Gps OFDM Visible Light Communication Using Light-emitting Diodes with Photonic Crystals

摘要

Recently, GaN based light-emitting diodes (LEDs) have been developed for visible light communication (VLC) with the increase of the usage in wireless data transmission. In this work, we successfully make the GaN-based LEDs with the photonic crystal (PhC) structure with high frequency response. Data transmission demonstrated using on-off keying (OOK) and 16- Quadrature Amplitude Modulation (QAM)- orthogonal frequency division multiplexing (OFDM) modulation methods on photonic crystal LEDs (PhCLEDs) and conventional LEDs (CLEDs).
