Abstract:
1. A method of designing a nanophotonic scattering structure, comprising: a) establishing an initial design for a nanophotonic scattering structure including an active layer and an adjacent scattering layer, the scattering layer having an array of discrete pixels wherein each discrete pixel has a geometric profile and is variable between at least two pixel height levels; b) identifying a performance metric for the nanophotonic scattering structure; c) varying a height of a pixel from the array of discrete pixels among the at least two pixel height levels, said performance metric being a function of the height; d) calculating the performance metric for the nanophotonic scattering structure; e) repeating steps c) and d) to increase the performance metric, unless the performance metric is not increased by varying the height of the pixel to any of the at least two pixel height levels; f) repeating steps c) through e) for each pixel within the array of discrete pixels until steps c) through e) have been performed for every pixel within the array of discrete pixels; and g) repeating steps c) through f) until the performance metric reaches an optimized value.
