In this paper, we experimentally demonstrate a high data rate visible light communication system by employing 450-nm Gallium Nitride laser diode. An achievable information rate of 10.23 Gbps over a 1.2m indoor free space transmission with normalized generalized mutual information above 0.92 is reported. This is achieved due to the use of probabilistic shaping bit loading scheme to maximize the spectral efficiency.
