Abstract:-Soft glasses like tellurite, bismuth- oxide-based glasses, and CHALCOGENIDE
glasses have intrinsic nonlinearities from 10 to 100 times than those of silica glass. Among these
soft glasses the Raman gain coefficients of chalcogenide glass fibres are almost 300 times higher
than that of silica fibres, and the Brillouin gain coefficient is more than 2 orders of magnitude more
than that of silica-based fibres. In addition chalcogenide shows low linear absorption, low twophoton absorption, and fast response time because of the absence of the free- carrier effects. As a
result, optical fibres made of chalcogenide glasses, are efficient a] for generating mid-IR nonlinear
phenomena, b] fabricating short active fibre devices and c] achieving fibre Raman and Brillouin
lasers. In particular, biomedicine and sensing will be strongly aided by these devices. New
communication and remote sensing systems operating in unexplored atmosphere wavelength
windows could become a reality. This paper reviews the deployment potential of chalcogenide
along with the application trends and improvements that are underway
