• 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 finite-difference 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.
