Abstract
Fused-taper wavelength division multiplexing (WDM) couplers for use in combining the 1480 nm pump wavelength with the 1540 nm signal wavelength of erbium-doped fibre amplifier systems are reported. Output port isolation in excess of 15 dB has been achieved at the centre of each channel with very low polarisation sensitivity of <0.2 dB over a 30 nm range about the channel centres.
