The main theoretical and experimental backgrounds of two-photon absorption (TPA) and TPA-induced free carriers in silicon are presented in detail. In particular, the mostly recent experimental achievements in applications of TPA and TPA-induced free carriers are discussed, such as optical limiting, optical pulse shaping, all-optical switching and modulation, all-optical logic gates, all-optical wavelength conversion and some applications of TPA in silicon photodiode. We show that TPA and TPA-induced free carriers in silicon can provide novel functional devices on chip scale, which would play important roles in the future optical communication and optical signal process systems.
