Complete leaky mode coupling in dual-core photonic crystal fibre based on the coupled-mode theory

doi:10.1088/1674-1056/20/6/064101

Abstract This paper theoretically investigates the dependence of leaky mode coupling between inner core fundamental mode and outer core defect mode on phase and loss matching in pure silica dual-core photonic crystal fibres with the multi-pole method. The complete mode coupling can take place when both the phase and loss matching conditions are satisfied at the avoided anti-crossing wavelength. It shows the influences of cladding structure parameters including the diameters of cladding air holes d₁, diameters of outer core holes d₂ and hole to hole pitch $\varLambda$ on the characteristics of leaky modes coupling. The coupled-mode theory is used to analyse the mode transition characteristics and the complete coupling can be clearly indicated by comparing the real and imaginary parts of propagation constant of the leaky modes.

Keywords: dual-core photonic crystal fibres complete leaky mode coupling multi-pole method coupled-mode theory
