Resumo
Core guidance within several bands in the visible region of the spectrum is observed and characterized in hollowcore photonic crystal fibers designed to operate at a wavelength of 1550 nm. Experiments show that in these transmission bands, light is likely to be confined to the core due both to antiresonance in the silica ring around the core and to low coupling to microstructured cladding modes. The bands present losses of ̃1 dB/cm and are highly dependent on the exact fiber structure and light polarization. Even small physical changes due to pressure are found to affect the transmission intensity and polarization. The response to pressure was then investigated, focusing on the development of sensors based on intensity or polarization interrogation. © 2012 Optical Society of America.
