Paper Abstract

We used a modified form of the Z-scan technique to study the various factors influencing bistability in a semiconductor doped glass filter. A strong self-focusing effect was observed and an estimate of the corresponding n2 coefficient is obtained. A systematic modeling of absorptive bistability in a semiconductor doped glass, including both longitudinal and transverse heat diffusion as well as the effects of self-focusing, is presented and compared with experimental observations.
