Abstract

The feasibility of optical wireless communication links using high-brightness illumination light-emitting diodes (LEDs) is experimentally verified. We measure the modulation bandwidths of red-, green-, and blue-colored LEDs and the eye patterns for optical wireless links incorporating single- and multi-LED transmitters. The eye patterns of single-color red, green, and blue LEDs are compared. An optical communication link consists of an optical transmitter module with seven LEDs, and a packaged silicon photodiode as a receiver. The bit error rate (BER) curves are measured by varying the link distance and the horizontal offset to check their dependencies on the BER. The optical wireless communication link incorporating the transmitter with seven high-brightness illumination LEDs can support 10-Mb/s data transmission without any optimized optical filter to enhance optical gain. Based on the experimental results, it is demonstrated that a communication link with illumination LEDs could be used for short-reach optical wireless communication systems.
