Coupling length and coupling loss in AlGaAs photonic crystal waveguides

Research Article


In this work, we present the theoretical simulation results of a two parallel plasmonic waveguides structure with same geometries. There is a low-index semiconductor AlGaAs layer between the GaAs layer and the metal layer. The coupling length and coupling loss are calculated at the telecom wavelength (1550 nm) for different structures by employing the finite-difference time domain.
