Reduction of the Degree of Polarisation of an Er-Doped Superfluorescent Fibre Source with a 3-Section Lyot Fibre Depolariser

摘要

A 3-Section Lyot Fibre Depolariser was used to substantially reduce the degree of polarisation of an Er-doped superfluorescent fibre source. The residual degree of polarisation of this improved Er-doped superfluorescent fibre source is found to be 0.05% (-33dB).
