“…Chalcogenide glasses based on S, Se, and Te have many unique optical properties which make them very promising materials for use in optical and microoptical elements such as gratings [1], optical recording media [2], fiber optics and waveguided devices in integrated optics since they exhibit a good transparency in the infrared region, especially at the telecommunication wavelengths at 1.3 and 1.55 lm [3]. Moreover, chalcogenide glasses posses a high third-order non-linearity with an ultrafast time response [1,[4][5][6][7].…”

“…Moreover, chalcogenide glasses posses a high third-order non-linearity with an ultrafast time response [1,[4][5][6][7]. The non-linear refractive index n 2 of Se-based chalcogenide glasses is generally higher than that of S based glasses because the Se-based glasses have higher linear refractive indices, i.e., glasses composed of heavier elements.…”

“…Therefore, micropatterning and nanopatterning of chalcogenide glass or thin-film optical devices play an important role for further enhancement of functionalities and applications. Micropatterning of chalcogenide glasses can be realized by a variety of techniques, such as traditional mask-based, multiphoton or direct UV lithography [6][7][8], holography [9,10], nanoimprint lithography employing hard or soft stamps [11][12][13], ink-printing [14], or direct laser writing (DLW) [15][16][17][18]. DLW has been already demonstrated as an effective method for fabrication of chalcogenide-based threedimensional (3D) photonic crystals [16], and optical waveguides in thin films [17], under surface "buried" multimode waveguides [18] or low-loss 3D mid-IR optical waveguides [19] in Ga-La-S glasses.…”

Direct laser writing of relief diffraction gratings into a bulk chalcogenide glass

We inscribed relief diffraction gratings with periods of 6, 14, and 24 μm into the surface of Ge15Ga3Sb12S70 bulk glass by the material's ablation using a femtosecond λ = 800 nm Ti:sapphire pulsed laser. The laser writing was done with sample implemented on a computer-controlled stage employing surface-to-beam alignment, laser power, and raster pattern control. Pulse energies of 1.5, 3.0, and 4.5 μJ were focused on spot diameter of 1.5 μm, resulting in channel widths, measured on the surface, of around 4, 5, and 6 μm and depths up to 1.7 μm. The first-order diffraction efficiency of the fabricated gratings was up to 10% at 650 nm. We have also fabricated a "composite" grating combining the three relief diffraction gratings inscribed in the same position, but with a mutual tilt. The composite grating provides complex multidirectional diffraction of the light in accordance with geometrical arrangement and grating period of all the gratings inscribed. We propose practical applications of femtosecond pulsed-laser surface patterning, for example, surface-relief diffraction microgratings integrated at the ends of multimode mid-IR chalcogenide optical waveguides or on the surfaces of bare core chalcogenide glass optical fibers used for chemical sensing. © 2012 Optical Society of America

“…Micro-and nano-patterning of chalcogenide glass (or thin film) based optical devices then plays an important role for further enhancement of their functionalities and applications. Micro-patterning of chalcogenide glasses can be realized by numerous techniques such as traditional mask-based, multi photon or direct UV lithography [6][7][8], holography [9,10], nano imprint lithography employing hard or soft stamps [11][12][13], ink-printing [14] or laser writing [15][16][17][18].

Direct laser writing has been already demonstrated for the fabrication of under surface "buried" 3D mid-IR waveguides in chalcogenide glasses by employing a large photo-induced refractive index change in the features formed in the path of the focused beam from a short pulse laser. In this paper, we report on direct laser writing of relief diffraction gratings with periods of 6, 14 and 24 μm into the surface of Ge 15 Ga 3 Sb 12 S 70 chalcogenide glass by using a 800 nm Ti:saphire femtosecond pulse laser. The first order diffraction efficiency of the fabricated gratings was over 60 % at 650 nm. We have also fabricated a "composite" grating composed of three relief diffraction gratings inscribed in the same position, but with a mutual tilt. Composite grating provided complex multidirectional diffraction of the light in the accordance with geometrical arrangement and grating period of all the gratings inscribed. The fabrication was implemented on a computer controlled stage employing surface-to-beam alignment, laser power and raster pattern control. Pulse energies of 1.5, 3.0 and 4.5 μJ were used, resulting in channel widths of around 4, 5 and 6 μm, respectively, and depths up to 1.7 μm. We propose practical applications including surface relief diffraction micro-gratings at the ends of multimode chalcogenide optical waveguides or on the surfaces of bare core optical fibers used for chemical sensing.
