Highly nonlinear bismuth oxide-based glass fibres for all-optical signal processing

Abstract
A highly nonlinear bismuth oxide (Bi2O3)-based glass fibre aiming at applications to all-optical signal processing is reported. This fibre features a high nonlinear coefficient γ of 64.2 W−1 km−1, low propagation loss of α=0.8 dB/m, low splicing loss of 0.48 dB, and high mechanical and chemical durability.
