Microstructured optical fibres with a wide single-mode range
Autor: A. N. Denisov, S. L. Semjonov
Publikováno v: Quantum Electronics. 51:240-247
We have proposed a new design of microstructured optical fibres (MOFs), containing three rings of identical circular holes around a core, with different separations between the rings. The properties of the MOFs have been analysed numerically using th
