Notes:
This paper investigates new technological devices to be utilised in future optical communications, by means of variational method (FEM) and multipole scattering approach (Rayleigh method). This last one provides interesting asymptotic results in the long-wavelength limit. The so-called photonic crystal fibres (PCF) possess radically different guiding properties due to photonic band gap guidance: removing a hole within a macro-cell leads to a defect state within the gap. In the case of multi-core PCF, the localised modes start talking to each other which possibly leads to a new generation of multiplexer/demultiplexers.
