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°. © 2011 American Institute of Physics.The authors would like to acknowledge support from the Defense Advanced Research Projects Agency under the Nanoscale Architecture for Coherent Hyperoptical Sources programme under Grant No. #W911NF-07-1-0277 and from the National Science Foundation through NSF CIAN ERC under Grant No. #EEC-0812072.
