All wavelengths and directions hybrid-guidance photonic crystal fiber and its property of Bragg grating resonance.Huijia Zhang, Shuguang Li, Chi Wah Leung, Helen L. W. ChanApplied optics2009We 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.
