Abstract
Er3+-doped single-polarisation optical fibres have been designed and fabricated, for the first time. The fabricated single-polarisation optical fibres transmitted only the x-polarisation mode in the wavelength region around 1.535 μm. The pump power wavelength was 1.48 μm and the pump power was about 29 mW. The x-polarisation mode has been amplified with a net gain of 14 dB for a fibre length of 27 m.Keywords
