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.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
