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.
