Recovery response of optical stopping effect on P2As20S78 and Sn1As20S79 film waveguide

Abstract

Effect of compressedon the size and stability of reverse micelles: Small-angle x-ray scattering and phase behavior study The Journal of Chemical Physics 118, 3329 (2003) The recovery response characteristics of optical stopping effect on the low-impurity As 20 S 80 system (P 2 As 20 S 78 and Sn 1 As 20 S 79 ) film waveguides are investigated in detail. Compared with As 20 S 80 , P 2 As 20 S 78 film waveguide deteriorates the response behavior of recovery propagation and is mainly characterized by the slow recovery propagation process with the disappearance of the fast rising edge. On the contrary, Sn 1 As 20 S 79 can improve evidently the earlier recovery stage by shortening response time of the rising edge to the milliseconds level, and also reduce the optical propagation loss. Experiments also show that the optical stopping effect can reach a saturated degree under He-Cd laser illumination for no less than 800 ms, and the addition of an assistant He-Ne laser may improve the recovery response slightly but not significantly.

Recovery process of optical stopping effect in tin or phosphorus-doped amorphous As2S8thin-film waveguide

“…We have reported the effect on optical stopping by trace doping with elements Sn or P [16]. For Sn, (1) Sn has smaller electron negativity and larger radius than As.…”
