Paper Abstract

In photonic crystal fiber technique a free choice of microstructure allows flexible design of multicore waveguides. In this paper we study properties of a double-core fiber with square and hexagonal lattices. They can be modified with local changes of a structure. Variable size of the central hole that separates cores influences mode coupling properties. Full-vector mode solver using the biorthonormal basis method is employed to analyze guiding properties of the double-core fiber. In FDTD numerical simulations we study coupling efficiency in fibers with various crystal structures. We present experimental realizations of solid double-core photonic crystal fibers fabricated from multi-component glass. Composition of oxides is chosen to obtain higher refractive index than available in fused silica and relatively low-loss guidance when compared to other silicate glasses. Transmission properties of double-core fibers are measured, inter-core coupling mechanism and possible applications are discussed.
