Field propagation study in ultra-small core photonic crystal fiber beyond the fundamental mode cut-off
Abstract We present the study of the behavior of the electromagnetic field propagating in the ultra-small core photonic crystal fiber (PCF) beyond its fundamental mode cut-off. We first the use plane waves expansion (PWE) method to find necessary parameters and then involve the finitedifference time-domain (FDTD) method accelerated with a graphic processing unit (GPU) for long-range light propagation simulation. The confinement losses beyond λ =1200 nm achieves tens of dB/cm, which can be lowered significantly by increasing the number of cladding rings.
