Abstract
The isolation of a wavelength-demultiplexing twin-core fibre with nomi nally identical cores is improved from 7dB to 26dB by increasing the r efractive index of one core. Tuning relaxes the fabrication tolerances necessary for greater than or equal to 20dB isolation between channel s, enhancing the feasibility of using twin-core fibres for demultiplex ing 1.3 and 1.55mu>m signals in communications systems.
