Precise Positioning and Orientation of Nanowire Lasers in Regular and Patterned Surfaces

Accurate integration of nanowire (NW) lasers with precise (sub-micrometric) control of their position and orientation angle with other photonic elements is demonstrated by means of a transfer-printing (TP) technique. 1- and 2-dimensional arrays of NW lasers are fabricated onto regular and diffractive photonic substrates with full control on the number of NWs in the arrays, their position, orientation angle and spacing between elements.The authors would like to acknowledge funding by the Australian Research Council and the UK EPSRC Doctoral Training Partnership.
