Femtosecond laser inscription of nonlinear photonic circuits in Gallium Lanthanum Sulphide glass

María Ramos Vázquez, Belén Sotillo, Stefano Rampini +6

We report on femtosecond laser writing of single mode optical waveguides in chalcogenide Gallium Lanthanum Sulphide (GLS) glass. A multiscan fabrication process was employed to cre…
