Abstract

A 19-cell hollow core photonic bandgap fiber with a core diameter of 20 mum and an attenuation minimum of about 11dB/km at 1590 nm was exposed to continuous Co gamma radiation and pulsed electrons up to dose values of 10⁴ Gy and 100 Gy, respectively. The attenuation increase during continuous or after pulsed irradiation was at least 30 times or 100 times lower, respectively, than observed with the best conventional single-mode fibers. Furthermore a slight reduction of the width of the transmission band after a total gamma dose of 1.4 10⁵ Gy was observed.
