External modulation is preferred over direct modulation. Some important reasons are reviewed in this paper. The performance of electro-optic modulator (external modulator) is reviewed for visible-light communication over direct modulation. Here, operating wavelength range is 400–700 nm and voltage-length product (VπL) is 0.8 V cm. Calculated insertion loss is very low compared to other available devices and the extinction ratio is very high.
