Polarisation-independent switching in a nonlinear optical loop mirror by a dual-wavelength switching pulse

摘要

Polarisation-independent all-optical switching has been demonstrated in a nonlinear optical loop mirror using a switching pulse comprising two waves of orthogonal polarisation and a few nanometre wavelength separation. Neither a polarisation-maintaining loop fibre nor polarisation adjustment of the switching pulse was required in the loop mirror to achieve polarisation-independent switching.
