High speed plastic optical fiber data links using LEDs
Plastic optical fiber (POF) data links have been widely viewed as a cost- and energy- effective solutions for short-reach Gigabit data communications such as in-home and automotive networks. POF also has excellent compatibility with low-cost light-emitting-diodes (LEDs). In this paper, we demonstrate a 4 Gb/s single micro-LED (μLED) PAM-16 link and a record 4.7 Gb/s multiple μLEDs PAM-8 link by 1) use of avalanche photodiodes (APD) in combination with high order modulation formats; and 2) illumination of multiple μLEDs. Both digital implementation based on FPGA and analogue implementation are considered for real-time transmitters.
