The nonlinear susceptibility and optical bistability of narrow gap semiconductors
The two-band model is improved and the nonlinear susceptibility of narrow gap semiconductors are calculated in this paper. Using the susoeptibility obtained, we deal with the optical bistability (OB) of InSb, and figure out the stationary state curve of OB, the relation between critical switching light intensity and frequency of incident light and the transient properties of OB, which are consistent with the experimental results.
