Abstract
Fabrication of strong fibre Bragg gratings in singlemode arsenic selenide (As2Se3) fibre for use at telecom wavelengths by the transverse holographic method is reported. Photoinduced decrease in the material refractive index was achieved using low-intensity CW illumination at a wavelength of 785 nm. A peak grating strength of 23.7 dB is seen, with inferred change in the average refractive index as large as 4.7 times 10-3.
