STUDIES ON THE DYNAMICS OF OPTICAL BISTABILITY SWITCHING IN THE INTERNAL FABRY-PEROT CAVITY WITH A CdSxSe1-x-DOPED GLASS CHANNEL WAVEGUIDE 下载免费PDF全文
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. 相似文献
