1 Gbps visible light communication system utilizing Mach–Zehnder Modulator

Visible light communication system poses challenges in the modulation schemes, in particularly relating to the flickering and dimming support which limits its data rate and real-time practical implementation. This article has proposed MZM devices which work on visible wavelengths, 520 and 530 nm, with improved performance characteristics as ER 36.9337 dB & 36.9183 dB, respectively, and IL 0.056 dB and 0.0714 dB, respectively. The proposed devices have also been analyzed in an indoor environment working on 1 Gbps at 10 - 5 to 10 - 4 BER range.
