Corrugated nanowires as distributed Bragg reflectors

Abstract Distributed Bragg reflectors (DBRs), comprised of periodic refractive index changes, are widely used in optoelectronic devices as resonators, filters and sensors. The heterostructures required for DBRs can be difficult to implement nanostructures due poor compositional control on the nanoscale. In present paper, simulation results presented reflectance spectra from DBR structures that implemented using perturbations a nanowire (NW) diameter, rather than heterostructures. corrugated NW structure produce stopband with near unity. wavelength tuned by adjusting pitch arrays, corrugation depth, period corrugation. proposed presents new paradigm wide range nanoscale device applications.
