Gbps Long-Distance Real-Time Visible Light Communications Using a High-Bandwidth GaN-Based Micro-LED

In this investigation, we experimentally demonstrated a high-speed Gbps long-distance real-time visible light communication system based on non-return-to-zero on-off keying modulation by using a high-bandwidth Gallium nitride-based micro-LED with a modulation bandwidth of ∼230 ...

Description
Summary:In this investigation, we experimentally demonstrated a high-speed Gbps long-distance real-time visible light communication system based on non-return-to-zero on-off keying modulation by using a high-bandwidth Gallium nitride-based micro-LED with a modulation bandwidth of &#x223C;230&#x00A0;MHz and a size of 40 <italic>&#x03BC;</italic>m <inline-formula><tex-math notation="LaTeX">$ \times $</tex-math></inline-formula> 40 <italic>&#x03BC;</italic>m. The maximum real-time data rate obtained is up to 1.3&#x00A0;Gbps at a 3&#x00A0;m free-space transmission distance with a bit-error rate (BER) of 3.4 <inline-formula><tex-math notation="LaTeX">$ \times $</tex-math></inline-formula> 10<sup> &#x2013;3</sup> and 1&#x00A0;Gbps at a 10&#x00A0;m distance with a BER of 3.2 <inline-formula><tex-math notation="LaTeX">$ \times $</tex-math></inline-formula> 10<sup>&#x2013;3</sup>, both of which are underneath the forward error correction threshold of 3.8 <inline-formula><tex-math notation="LaTeX">$ \times $</tex-math></inline-formula> 10<sup>&#x2013;3 </sup> required for free-error operation. In addition, when the transmission distance is increased to 16&#x00A0;m in free space through reflecting the emission light beam by blue reflectors mounted on the wall, a data rate of 0.87&#x00A0;Gbps with a BER of 3.5 <inline-formula><tex-math notation="LaTeX">$ \times $</tex-math></inline-formula> 10<sup>&#x2013;3 </sup> is achieved successfully.
