Abstract :
By near-field coupling a high-gain CdSe nanowire (NW) and a 100-nm-diameter Ag NW, we demonstrate a hybrid photon-plasmon laser operating at 723-nm wavelength at room temperature, with a plasmon mode area of 0.008λ2. This device simultaneously provides spatially separated photonic far-field output and highly localized coherent plasmon modes with sub-diffraction-limited beam size.
