We demonstrate room temperature, continuous-wave lasing with enhanced far field emission directionality in coupled-cavity photonic crystal lasers, made with InAsP/InP quantum well material. These surface-emitting lasers can have a very low effective threshold power of 14.6 µW, with a linewidth of 60 pm, and 40% of the surface emitted power concentrated within a small divergence angle of ±30°
