We present a broadband free space light communication using high-speed micro organic light emitting diode (OLED) as transmitter. We report first the design and bandwidth measurements of innovative OLEDs whose size are in the range of tens of micrometres. For OLEDs with reduced active area such as 40 µm x 40 µm, a cut-off frequency up to 345 MHz is reached. Then a free-space optical wireless link is build based on these high-speed micro-OLED. Using Direct Current Optical-Orthogonal Frequency Division Multiplexing) with adaptive bit and energy loading, we achieve a data rate of 2.85 Gb/s.

Optical Camera Communications (OCC) is a technology that allows for high-speed data transfer through visible light. The technology is popular in various industries, including retail, museums, and other locations where reliable and fast data transfer is required. OCC works by using LEDs to transmit data through light waves, which can then be received and interpreted by cameras or other optical sensors.
