摘要: An equivalent refractive index mathematic model is presented according to the geometrical structure of multi-coating D-shaped fibres, and analysis loss characteristics this kind fibre given. The results indicate that losses propagation modes in are related distance between polished plane core, thickness polymer adhesive. This provides theoretical instructions for us choose suitable parameters devices. Since different states polarization different, a will possess extinction characteristic.
