A single-mode photonic crystal fiber (PCF) with low chromatic dispersion, low bend, and rotational sensitivity is presented. The transverse electric field vector distributions of the fundamental, higher order and fundamental space filling modes, their effective indices, chromatic dispersion, confinement, bending and rotational losses are reported using full-vector finite-element method (FEM). In addition, the endlessly single mode behavior is demonstrated by employing the V parameter of the proposed PCF. It has also been shown that the proposed PCF design is insensitive to bends and rotations.
