摘要: We report the optical bistability in CdSxSe1-x-doped glass channel waveguide with rise and fall times of about 24 and 30ps, respectively, in bistable switching by means of fiber coupling input with a power of about 3mW. The third-order nonlinear susceptibility (x(3)) of CdSxSe1-x-doped glass is estimated experimentally to be 1.8×10-9 esu. The high speed switching and the value of x(1) show that the optical bistability is caused by an optical nonlinearity which can be attributed to the band-filling effect.

Abstract: We report the optical bistability in CdSxSe1-x-doped glass channel waveguide with rise and fall times of about 24 and 30ps, respectively, in bistable switching by means of fiber coupling input with a power of about 3mW. The third-order nonlinear susceptibility ($\chi$(3)) of CdSxSe1-x-doped glass is estimated experimentally to be 1.8×10-9 esu. The high speed switching and the value of $\chi$(1) show that the optical bistability is caused by an optical nonlinearity which can be attributed to the band-filling effect.
