We propose a hybrid-guidance photonic crystal fiber (HG-PCF) that can guide light by the simultaneous effect of index guidance and photonic bandgap guidance at all wavelengths and directions. Index guidance is the dominant guidance mechanism at short wavelengths and photonic bandgap guidance is the dominant guidance mechanism at long wavelengths. The transmission spectrum of the Bragg grating in such a HG-PCF is also investigated.
