摘要：

We demonstrate a compact hybrid structure red-green-ultraviolet three-color laser consisting of three distinct semiconductor nanowires (CdSe, CdS and ZnO) attached to a silica microfiber, which is pumped by 355 nm wavelength laser pulses. The exciting of the nanowires and the collection of the photoluminescence (PL) are implemented by means of evanescent coupling through the same silica microfiber. When pump energy higher than 1.3 mu J, three spatially and spectrally distinct lasing groups can be measured at the same output port simultaneously. The approach can be extended to other materials to produce hybrid lasers that cover ultraviolet to near infrared spectral regions. (C) 2009 Optical Society of America
