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.

“…In particular, luminescence and waveguiding properties of single nanowires have been reported in view of their applications as lasers or efficient optical cavities in photonic devices. [1][2][3][4][5][6][7][8][9][10][11][12] The high crystalline quality and the commonly flat surfaces of nanowires are valuable points to consider them very good candidates to explore their behavior as optical resonators. Fabry-Perot (FP) modulations due to reflections between wire flat ends and whispering gallery modes (WGMs) due to total internal reflections in microstructures with regular polyhedral cross-sections were reported in some semiconducting micro and nanostructures.…”

“…1(b) is obtained where the two bright emission spots are visible at the two ends of the nanowire, which indicate that the nanowire acts as a transparent waveguide for the emitted photoluminescence. [7][8][9] Strong modulation in the PL spectra of the nanowires due to the Fabry-Perot (FP) interferences as a result of the multiple reflections between the wire's end facets 10 is shown in Fig. 2(a).…”

We investigate the optical emission of wurtzite GaP/Al0.4Ga0.6P core/shell nanowires (NWs) transferred to a SiOx substrate to demonstrate a high degree of waveguiding of the emitted photoluminescence (PL) signal. By analysing the Fabry-Pérot mode spacing in combination with calculations of the guided modes in the NWs, we calculate a very high refractive index of bulk WZ GaP of 4.2 at a wavelength of 600 nm. The measured quality factors up to 600 indicate the excellent optical quality of the nanowire resonator.
