| Abstract: | Based on effective medium approximation, self-consistent mean field approximation and the spectral representation method were adopted to investigate the temperature dependence of optical bistability of metal/dielectric granular composite. Numerical calculations were used to find out the temperature effects on optical bistability at different values of incidence frequency, volume fraction and shape factor. The results show that the emergence of optical bistability, optical bistability threshold and threshold width are all greatly dependent upon the temperature. |
