“…The introduction of micro-LEDs has enabled high-performance value-added lighting functions such as VLC and indoor positioning and tracking [3]. Micro-LEDs are known for their small active areas enabling high current density injection, which drives the modulation bandwidth to hundreds of megahertz [4,5]. At 450 nm, micro-LEDs have set the standard for high-speed VLC.…”

Visible light communication (VLC) is a promising solution to the increasing demands for wireless connectivity. Gallium nitride micro-sized light emitting diodes (micro-LEDs) are strong candidates for VLC due to their high bandwidths. Segmented violet micro-LEDs are reported in this work with electrical-to-optical bandwidths up to 655 MHz. An orthogonal frequency division multiplexing-based VLC system with adaptive bit and energy loading is demonstrated, and a data transmission rate of 11.95 Gb/s is achieved with a violet micro-LED, when the nonlinear distortion of the micro-LED is the dominant noise source of the VLC system. A record 7.91 Gb/s data transmission rate is reported below the forward error correction threshold using a single pixel of the segmented array when all the noise sources of the VLC system are present.

“…Very recently, a data rate of 1 Gbit/s with improved modulation bandwidth was reported by using an LED with an unconventional phosphor with a short relaxation lifetime (100 of ps) to produce yellowish white emission [11]. In order to increase the LED modulation bandwidth limited by RC parasitics, micro LED arrays have been used to achieve data rates up to 500 Mbit/s using a non-return-to-zero on-off keying (NRZ-OOK) modulation [7,12,13]. To improve the data transmission, 3 Gbit/s of higher order modulation has been performed using orthogonal frequency-division multiplexing (OFDM) with a single micro LED [14].…”

El-Desouki, Munir M.; Speck, James S.; Nakamura, Shuji; Ooi, Boon S.; DenBaars, Steven P. Abstract:We demonstrate data transmission of unfiltered white light generated by direct modulation of a blue gallium nitride (GaN) laser diode (LD) exciting YAG:Ce phosphors. 1.1 GHz of modulation bandwidth was measured without a limitation from the slow 3.8 MHz phosphor response. A high data transmission rate of 2 Gbit/s was achieved without an optical blue filter using a non-return-to-zero on-off keying (NRZ-OOK) modulation scheme. The measured bit error rate (BER) was less than the forward error correction (FEC) limit of 3.50 × 10 -3 . The generated white light exhibits CIE 1931 chromaticity coordinates of (0.3628, 0.4310) with a color rendering index (CRI) of 58 and a correlated color temperature (CCT) of 4740 K when the LD was operated at 300 mA. The demonstrated laserbased lighting system can be used simultaneously for indoor broadband access and illumination applications with good color stability. Kruglov, and O.

“…In this work we propose to use light emitting diodes (LED) as the optical source mounted at BSs to flood the incoming trains. LEDs are capable of delivering very high data rates in excess of 500 Mbps [6] and 1 Gbps [7], which would be ideal for ground-to-train communication links. Also, reliability, simple drive circuitry and low cost are some distinct advantages of LEDs over lasers [8].…”

Abstract-There is a increasing demand for high speed data services while travelling on trains and other means of public transportation. Hence, an alternative technology to radio frequency (RF) communications called free space optics (FSO) could be used to provide truly high-speed broadband services in trains. This paper presents a Lambertian source modelling of FSO ground-to-train communication link along with its link performance analysis. Here, we investigate the use of a single optical base station (BS) that can provide the coverage range up to 75 m at 10 Mbps using on off keying (OOK) non-return to zero (NRZ) data signal with a bit error rate (BER) of 10 -6 .
