Abstract
Nonlinear refractive index (n2) of chalcogenide‐glass (As2S3) fibers has been evaluated for the first time from spectral broadening due to self‐phase modulation. The obtained value of n2 was 1.7×10−14 (cm2/W) which is two orders of magnitude higher than the value with silica‐glass fiber. This large n2 value is useful in reducing switching power and size when fiber is used for all‐optical switches.Keywords
