Multicore structures based on increased index waveguiding traces are fabricated by ultrafast laser photo inscription in bulk optical glass. A parametric study of the geometry of structure, number of traces and index contrast is discussed with respect to guided modes characteristics. Multicore waveguide present optical designs allowing large mode area light guiding by ultrafast laser photo inscription with coherent mode superposition in near infrared and mid-infrared in fused silica and Chalcogenide glass.
