Beyond 100 m Range Mini-LED-Based Visible Light Communication System

Photonics
In visible light communication (VLC) systems, lenses are typically used to collimate light at the transmitter. However, due to the wide light emission angle of mini-LEDs, capturing light at large angles using a lens at the transmitter can be challenging.
