Infiltration of glass matrices inside Photonic Crystals Fibres (PCFs) for achieving photonic bandgap (PBG) guidance and
expand devices development capabilities has been recently demonstrated. Herein, we report the fabrication of an all-solid
PBG guiding PCF by suction-assisted infiltration of molten silver-metaphosphate (AgPO3) glass into the air capillaries of
a commercial solid core PCF. The relatively low viscosity of the AgPO3 glass melt permitted infiltration at ~ 700 °C
inside an annealing oven apparatus by applying suction with the use of a standard mechanical vacuum pump, while its
low glass transition temperature of ~ 190 °C allows structural relaxations at temperatures close to ambient and the
formation of high quality glass strands inside the silica structure of the PCF. The AgPO3/silica PCF was characterized by
means of its transmission spectrum that showed PBG guidance over the measurement range (350-1650nm). The effect of
the AgPO3 glass photosensitivity on the guiding properties of the AgPO3/silica PCF was explored by employing a 355nm, 150 ps laser irradiation. The exposure gave rise to a photo-induced enhancement of the transmission-to-stop-band
extinction ratio by ~60 dB/cm as well as bandwidth tuning. Numerical calculations of the transmission spectra of the
AgPO3/silica PCF have been performed for confirming the experimental results and modelling the photo-induced
variation of the two-glass fibre transmission. We believe that the fabrication of the AgPO3/silica PBG fibre constitutes a
strong base for the development of new in-fibre sensing and scattering-based devices, by exploiting the high photosensitivity of silver and its specific plasmon absorption properties.
