Abstract
A novel waveguide with excellent optical properties can be easily produced. The photonic nanowires based waveguide has a) a plurality of nanowires; each nanowire having a ridge shape; b) the nanowires are supported by a support substrate or partially or totally free standing; c) the support substrate further supports interfacing waveguides disposed on both sides of the plurality of nanowires. The special concept of present invention allows to align a number of ridge-shaped nanowire that enables to control the amount of light being outside the solid waveguide in the evanescence field. Further, the design is compatible with solid waveguides and offers the possibility to confine (guide the light) within a multiple waveguide arrangement.
