We report emission from a bismuth doped chalcogenide glass which is flattened, has a full width at half maximum (FWHM) of 600 nm, peaks at 1300 nm and covers the entire telecommunications window. At cryogenic temperatures the FWHM reaches 850 nm.... Read More about Ultrabroad emission from a bismuth doped chalcogenide glass.

Compositional optimization of bismuth-doped yttria–alumina–silica glass (2009)
Journal Article
Hughes, M., Suzuki, T., & Ohishi, Y. (2009). Compositional optimization of bismuth-doped yttria–alumina–silica glass. Optical Materials, 32(2), 368-373. https://doi.org/10.1016/j.optmat.2009.09.004

We fabricated three series of glasses in which the Y2O3, Bi2 O3 and Al2O3 contents of Bi-doped Y2O3:Al2O3:SiO2 glass were varied. We optimized the content of each component based on quantum efficiency (QE) and other optical properties. The strengt...

Spectral broadening in femtosecond laser written waveguides in chalcogenide glass (2009)
Journal Article
Hughes, M., Yang, W., & Hewak, D. (2009). Spectral broadening in femtosecond laser written waveguides in chalcogenide glass. Journal of the Optical Society of America B, 26(7), 1370-1378. https://doi.org/10.1364/JOSAB.26.001370

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... Read More about Spectral broadening in femtosecond laser written waveguides in chalcogenide glass.
