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
