摘要：

Lasing emission has been observed in optically pumped DCM-poly(methyl methacrylate)-based spiral-shaped micropillar cavities. By transverse ring shaping of the pump beam, unidirectional laser emission is being clearly favored. The resulting improved far-field directionality evidenced by our imaging technique is shown to originate from the notch of the spiral microcavities. (c) 2005 American Institute of Physics.
