“…This was reconsidered in an investigation into the modal properties of hybrid plasmonic waveguides [130]. We must also note that Atwater's group studied the influence of a plasmonic core/shell nanowire resonator on the Purcell factor of a III-V semiconductor nanowire [39]. Bian et al conducted further theoretical studies on nanowire-based hybrid plasmonic structures for low-threshold lasing, well below the wavelength scale [10].…”

Abstract:We review principles and trends in the use of semiconductor nanowires as gain media for stimulated emission and lasing. Semiconductor nanowires have recently been widely studied for use in integrated optoelectronic devices, such as light-emitting diodes (LEDs), solar cells, and transistors. Intensive research has also been conducted in the use of nanowires for subwavelength laser systems that take advantage of their quasione-dimensional (1D) nature, flexibility in material choice and combination, and intrinsic optoelectronic properties. First, we provide an overview on using quasi-1D nanowire systems to realize subwavelength lasers with efficient, directional, and low-threshold emission. We then describe the state of the art for nanowire lasers in terms of materials, geometry, and wavelength tunability. Next, we present the basics of lasing in semiconductor nanowires, define the key parameters for stimulated emission, and introduce the properties of nanowires. We then review advanced nanowire laser designs from the literature. Finally, we present interesting perspectives for low-threshold nanoscale light sources and optical interconnects. We intend to illustrate the potential of nanolasers in many applications, such as nanophotonic devices that integrate electronics and photonics for next-generation optoelectronic devices. For instance, these building blocks for nanoscale photonics can be used for data storage and biomedical applications when coupled to on-chip characterization tools. These nanoscale monochromatic laser light sources promise breakthroughs in nanophotonics, as they can operate at room temperature, can potentially be electrically driven, and can yield a better understanding of intrinsic nanomaterial properties and surface-state effects in lowdimensional semiconductor systems.

“…A number of experiments have demonstrated that these cavities have a significant Purcell factor [4,10]. Others have also pointed out that these cavities can have high Purcell factors over a broad bandwidth and that even for light-emitting diode applications they are interesting [16].

“…Considering that semiconductor gains can reach several thousands per centimeter, there is room to make devices where a large proportion of the lasing mode energy is coupled out. Others have also indicated that for both lasers and LEDs, such pillar structures can in theory have quite acceptable efficiencies, in the order of 50% [16,21]. For the propagating mode devices, controllable out coupling is achieved by adjusting the transmission characteristic of one of the mirrors, which with a metal mirror means controlling its thickness [17].…”

There has been considerable interest in metallic nanolasers recently and some forms of these devices constructed from semiconductor pillars can be considered as surface-emitting lasers. We compare two different realized versions of these nanopillar devices, one with a trapped cutoff mode in the pillar, another with a mode that propagates along the pillar. For the cutoff mode devices we introduce a method to improve the output beam characteristics and look at some of the challenges in improving such devices.

“…Moreover, in many cases, for a relatively small modal volume, the optical modes of conventional cavities cannot match the modes to form the plasmon polaritons required by momentum and energy conservation for the efficient coupling. In contrast, plasmonic resonant cavities are capable of confining light at the nanometer scale, which leads to both enhanced local electromagnetic fields [5][6][7][8][9] and low mode volumes, [1,[9][10][11][12] and suggest promising applications for subwavelength optics and nanolasers, [13][14][15][16] nanoantennas, [17][18][19] sensing, [20][21][22][23] enhanced nonlinear effects, [18,[24][25][26][27] Surface enhanced Raman scattering, [8] and solar cell elements, [28,29] to name a few.…”

Plasmonic structures are known to confine light at the nanometer scale, and they exhibit enhanced electromagnetic fields localized in small mode volumes. Here we study plasmonic resonators based on a metamaterial consisting of periodic arrays of gold nanotubes embedded into anodic aluminum oxide and demonstrate strong confinement of local fields with low losses. We observe higher-order resonance modes of surface plasmons localized in gold nanotubes when the nanotube length exceeds some critical values. Our numerical simulations suggest that for the higher-order modes, the electric fields are mainly localized at the interfaces between aluminum oxide and gold in the form of the standing-wave longitudinal plasmonic modes, partially localized in the pores and at two ends of the nanotubes owing to the strong coupling of the Fabry-Pérot resonances with extraordinary optical transmission in the periodical structures through the inner nanochannels of the nanotubes, so that the nanotubes play a role of efficient cavity resonators. We reveal the existence of hybrid resonant cavity modes with asymmetrical distributions of the electric field resulting from the near-field coupling of both transverse and longitudinal modes in the gold nanotube metamaterials.3
