Abstract:Microlenses were fabricated through a thermal process using laser-induced localized overheating on the surfaces of various bulk Ge–Sb–S glasses. These glasses spanned three distinct groups: (a) stoichiometric (GeS2)1−x(Sb2S3)x glasses with x = 0–0.88; (b) a series with a constant Sb content represented as GexSb0.17S0.83−x, x = 0.13–0.24, and (c) glasses with a constant Ge content denoted by Ge0.18SbxS0.82−x, x = 0.03–0.10. A continuous-wave laser emitting at 532 nm was used in the fabrication process. Both the… Show more
