“…At 87 nJ/pulse an asymmetric triple-peak structure is evident. The triple peak is indicative of a 2.5 phase shift [45][46][47], and its weighting towards the long wavelength side of the pump is indicative of stimulated Raman scattering (SRS) [48,49].…”

Spectral broadening in femtosecond laser written waveguides in chalcogenide glass

Nonlinear spectral broadening to 200 nm, from an initial width of 50 nm, has been demonstrated in gallium lanthanum sulphide glass waveguides from 1540 nm, 200 fs pulses at 30 nJ/pulse. A formation mechanism is presented for these femtosecond laser written waveguides, based on optical characterization and comparisons to previous work. Two different types of waveguide are identified. One has a characteristic long narrow structure and is formed through filamentation caused by self-focusing. The other has a characteristic "teardrop" structure, which is formed by a type IIA photosensitivity mechanism and cumulative heating of glass around a central laser-exposed region.

“…It is well known that chalcogenide glasses are promising candidates for such improvements, and thus they have an important potential for non linear optics [5][6][7]. During the last decade, a great attention has been paid to the development of chalcogenide glass waveguides, including microstructured optical fibres, for different applications such as light amplification, optical regeneration and supercontinuum generation [8][9][10][11][12][13][14][15][16][17]. In this context, the ability to elaborate efficient highly non linear single-mode chalcogenide optical fibres, with desired performance parameters, as well as the development of approaches to monitor these parameters are of great importance.…”

Abstract:We report the fabrication and characterization of the first guiding chalcogenide As 2 S 3 microstructured optical fibers (MOFs) with a suspended core. At 1.55 µm, the measured losses are approximately 0.7 dB/m or 0.35 dB/m according to the MOF core size. The fibers have been designed to present a zero dispersion wavelength (ZDW) around 2 µm. By pumping the fibers at 1.55 µm, strong spectral broadenings are obtained in both 1.8 and 45-m-long fibers by using a picosecond fiber laser. C.

“…The high photosensitivity resulting from the inherent structural flexibility in chalcogenide glasses enables its utilization in writing Bragg gratings in fiber as well as waveguides3. As a result of the aforementioned qualities, chalcogenide glasses are highly promising for all–optical signal processing such as switching, wavelength conversion and regeneration4567.…”

GeSbS ridge waveguides have recently been demonstrated as a promising mid – infrared platform for integrated waveguide – based chemical sensing and photodetection. To date, their nonlinear optical properties remain relatively unexplored. In this paper, we characterize the nonlinear optical properties of GeSbS glasses, and show negligible nonlinear losses at 1.55 μm. Using self – phase modulation experiments, we characterize a waveguide nonlinear parameter of 7 W−1/m and nonlinear refractive index of 3.71 × 10−18 m2/W. GeSbS waveguides are used to generate supercontinuum from 1280 nm to 2120 nm at the −30 dB level. The spectrum expands along the red shifted side of the spectrum faster than on the blue shifted side, facilitated by cascaded stimulated Raman scattering arising from the large Raman gain of chalcogenides. Fourier transform infrared spectroscopic measurements show that these glasses are optically transparent up to 25 μm, making them useful for short – wave to long – wave infrared applications in both linear and nonlinear optics.
