Abstract

Broadband chirped fibre Bragg filters centred at 980nm and 1480nm with reflectivities as high as 99% and reflection bandwidths up to 22nm are reported. The filters have a low transmission loss of <0.5 db between 1.51 and 1.56μm and their application to reject and recycle unabsorbed pump light from a fibre amplifier is demonstrated.
