Wavelength combining fused-taper couplers with low sensitivity to polarisation for use with 1480nm-pumped erbium-doped fibre amplifiers
Fused-taper wavelength division multiplexing (WDM) couplers for use in combining the 1480nm pump wavelength with the 1540nm signal wavelength of erbium doped fibre amplifier systems are reported. Output port isolation in excess of 15dB has been achieved at the centre of each channel with very low po...
