A new GeS2-based chalcohalide glass was synthesized by the melt-quenching technique for nonlinear optical applications. A large glass-forming region was defined, and a wide infrared transmission was measured. Marked optical third-order nonlinearity was measured (n2 ˜ 7.5 x 10-5 cm2/GW), making this glass one of the best candidates for ultrafast nonlinear optical applications. All-optical switching in the second telecommunication window (? = 1.31 µm) by control of the optical pulse intensity in a twin-core-fiber directional coupler was numerically modeled, and a crossover length of 9.25 mm was calculated. © 1998 Optical Society of America.
