A novel type of hybrid plasmonic waveguiding structure that integrates semiconductor and metallic nanowires has been proposed and investigated at telecommunication wavelengths. Semiconductor nanowires symmetrically placed on both sides of a metallic nanowire provide an additional degree of freedom for tuning the characteristics of the plasmonic nanowire mode. Theoretical analysis reveals that at appropriate...
A novel type of plasmonic nanolaser based on coupled nanowires consisting of a gain material and a core/shell metal/dielectric nanowire is proposed. It shows the potential to enable deep-subwavelength lasing with low pump thresholds.
A novel hybrid plasmonic waveguide based on a triangular metal wedge is proposed. The structure could achieve ultra-deep-subwavelength mode confinement with low-loss, while its mode properties are still quite tolerant to fabrication errors.
