Detailed study of macrobending effects in a wide transmission bandwidth hollow-core photonic bandgap fiber.

Abstract

We study in detail the macrobending effects in a wide transmission bandwidth (~200nm) 19 cell hollow-core photonic bandgap fiber operating at 1550nm. Our results indicate low bend sensitivity over a ~130nm wide interval within the transmission window, with negligible loss (<0.1dB) for bending radii down to 5mm. The “red shift” and “blue shift” of the bandgap edge have been observed at the short and long wavelength edges, respectively. The cutoff wavelengths where air-guiding modes stop guiding can be extracted from the bending loss spectra, which matches well with the simulated effective refractive index map of such fiber. © (2016) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
