ABSTRACT:
An all-fibre mirror for use in fibre cavities and resinators for an all-fibre laser. The all-fibre mirror has a polarization selective fused taper optical fibre coupler including two pairs of optical fibres joined by a coupling region, with the fibres extending from one end of the coupling region being joined together so as to form a fibre loop. A polarization selection device interacts with the fibre loop to alter the polarization of the light passing through the loop.
