An accurate analysis of the single-mode properties of modified honeycomb photonic bandgap fibers with different geometric characteristics has been carried out by calculating the confinement losses of the fundamental and the higher-order modes. Simulation results have shown that confinement loss lower than 0.1 dB/km and an effectively single-mode behaviour over a wavelength range of about 150 nm can be achieved with a 8 air-hole ring fiber.
