Abstract
An asymmetric directional coupler (ADC) scheme for the efficient injection of light into slow light slot photonic crystal waveguides is proposed and investigated using finite-difference time-domain simulation. Coupling wavelengths can be controlled by controlling the geometrical parameters of a side-coupled subwavelength-corrugated strip waveguide. The coupling efficiencies for group index of 13, 23 and 35 are −0.8dB, −1.6dB and −2.7dB, respectively, with corresponding bandwidths of 13nm, 2.2nm and 2.3nm, respectively.
