Abstract : We experimentally demonstrate controllable nonlinear modulation of optical guiding in ultrafast laser-written evan-
escently coupled waveguide arrays in bulk gallium lanthanum sulfide chalcogenide glass. The intensity-dependent
response is validated by simulating light propagation in waveguide arrays with instantaneous Kerr nonlinearity
using a discrete continuous spatiotemporal unidirectional Maxwell equation model. The intensity-driven
modulation of transmission in multicore structures acts as a potential saturable absorber at kilowatt threshold
