Over 10 Gbps VLC for Long-Distance Applications Using a GaN-Based Series-Biased Micro-LED Array
IEEE Photonics Technology Letters(2020)
摘要
By employing a GaN-based series-biased micro-light emitting diode (
$\mu $
LED) array and orthogonal frequency division multiplexing modulation format, a high-speed free-space visible light communication system for long-distance applications has been demonstrated. The blue series-biased
$\mu $
LED array, which consists of
$3\times 3$
, 20
$\mu \text{m}$
-diameter
$\mu $
LED elements, presents promising performance with an optical power and −6dB electrical modulation bandwidth of over 10 mW and 980 MHz, respectively. Record data transmission rates have been successfully achieved at different free-space distances. Within 5 m transmission distances, over 10 Gbps data rates at the forward error correction (FEC) floor of
$3.8\times 10^{-3}$
are accomplished. Extending the transmission distances to 20 m, the data rates are maintained at the Gbps level at the FEC floor.
