A novel highly birefringent photonic crystal fiber with small effective mode area is proposed.

The nonlinear coefficient is about 12.6456 W−1 km−1, the fundamental mode area is about 10.2579 μm2.

The 2D FDTD method is used to design a tapered photonic crystal fiber, where large mode area is prominently coupled to optical fiber.

For the first time, we observed that the mode area is stabilized with respect to possible fabrication tolerance by implementing a secondary surrounding waveguide with configuration of large air holes in the outer ring.

Simulation results show that, the magnitude of confinement loss can be reduced to a value of 5.5012 × 10−6 dB/km at the operating wavelength 1550 nm for the structure with d/R = 0.8 and the corresponding effective mode area is 3.78046 μm2 and nonlinear coefficient is 0.03313 km−1W−1.

The calculated effective mode area is 16.01 μm2 at 1550 nm, corresponding to a coupling loss of 1.35 dB to the Corning SMF28 fiber, the confinement loss and bending loss with 1 cm bending radius less than 0.058 dB/km and 0.315 dB/km at 1550  nm, respectively.

Low confinement losses and small effective mode area are obtained at the same time.

The influences of fiber parameters on cutoff wavelength, bending loss and effective mode area are investigated systematically.

A novel parabolic-profile single-mode fiber with ultra-low bending loss and large-mode-area is proposed in this paper.

In reflection mode, the same area is seen as being whiter.

The present waveguide not only significantly improves the propagation length but also maintains a compact mode area, which is due to the coupling between the dielectric waveguide mode and plasmonic mode.
