Design and fabrication of birefringent splittable composite (BISPEC) fibre for polarisation-maintaining devices

摘要

The authors propose a new type of fibre, the birefringent splittable composite (BISPEC) fibre designed for polarisation maintaining optical devices. In addition to the good polarisation axis alignment (within 1 degrees ), this fibre has the added important property that it can readily be split to allow for standard fibre connection by fusion splicing.
