Here we present a hybrid photonic crystal fibre that allows phase-matching for third-harmonic generation, and therefore for triplet photon generation, between fundamental modes only. The fibre features an inner all-solid band-gap microstructure made of high refractive-index glass rod (SF6) embedded in a lower refractive index host (LLF1). This microstructure is part of a larger step-index PCF, where the longer wavelength radiation propagates by total internal reflection, without being perturbed by the all-solid microstructure. Combined with the difference in modal diameters, phase-matching is achieved between fundamental modes. Experimentally, we have observed third harmonic generation between 1521 nm and 507 nm.
