“…Light confinement phenomena in nanowires will be thoroughly addressed in the following section, which is definitely the most fundamental interpretation that penetrates overall vertical nanowire applications introduced in this review. Hence, the study of spectral resonances in nanowires based upon cylindrical optical waveguide theory paved the route to utilize vertical nanowires as a building block for spectral filters which not only can sensitively respond specific photon wavelength but also can convert light to photocurrent, expanding color gamut representation and photodetector applications (e.g., artificial retina and flexible imagers) [27][28][29][30]. Structure engineering of vertical nanowires can be conducted by additional shaping steps such as reactive ion etching (RIE), thermal oxidation and potassium hydroxide (KOH) etching, while precisely controlling the nanowire diameters, height and morphology [31][32][33].…”

Over the past few decades, nanowires have arisen as a centerpiece in various fields of application from electronics to photonics, and, recently, even in bio-devices. Vertically aligned nanowires are a particularly decent example of commercially manufacturable nanostructures with regard to its packing fraction and matured fabrication techniques, which is promising for mass-production and low fabrication cost. Here, we track recent advances in vertically aligned nanowires focused in the area of photonics applications. Begin with the core optical properties in nanowires, this review mainly highlights the photonics applications such as light-emitting diodes, lasers, spectral filters, structural coloration and artificial retina using vertically aligned nanowires with the essential fabrication methods based on top-down and bottom-up approaches. Finally, the remaining challenges will be briefly discussed to provide future directions.
