The model characteristics of ARROW structures

The model characteristics of antiresonant reflecting optical waveguide (ARROW) structures are analyzed by the transverse resonance method as well as some approximate methods. The difference between leaky modes and quasi-guided modes is investigated, and several formulas to calculate the attenuation coefficients of the modes are compared and validated for the ARROW structures. The effects of tunneling leakage and material absorption on the dispersion and the attenuation of the modes are examined in the analysis.<
