Schematic illustration of a hybrid photon-plasmon NW laser. (a) The hybrid photon-plasmon NW laser is composed of an Ag NW and an ultralong CdSe NW coupled into X-shape using a fiber probe for micromanipulation. The right segment of CdSe NW serves as a distributed absorber without reflection. (b) Closed-up view of the coupling area indicating the coupled hybrid cavity (marked by the dashed line), which serves as the hybrid photon-plasmon lasing cavity. (c) Cavity formation in the X-structure. (d) Lasing spectra collected from the Ag end-facet under pump fluences of 27−97 μJ cm−2.
