Abstract
The mini-stopband (MSB) of a W3 line-defect photonic crystal waveguide is used as a mirror for a GaAs based quantum-dot laser. Single mode, continuous-wave lasing is demonstrated for broad area lasers up to a current of 125 mA (2.7 x laser threshold), which demonstrates the high degree of mode selectivity of the MSB mirror. FDTD calculations indicate that optimisation of the mirror interface could lead to a further fourfold increase in reflectivity resulting in significantly reduced thresholds.
