Title :
Single-mode single-polarisation fibre using resonant absorbing effect

Abstract :
Modes of two parallel fibres exhange energy completely only when their propagation constants are identical. When one fibre is birefringent, and the other isotropic and lossy, the energy of one polarisation mode swaps back and forth between two fibres and is eventually absorbed.
