Summary: The objective of this paper is to introduce a new approach to the design of fully automated components fotónicos nanostructured including full inspection of the scattered light. This objective has been achieved with the development of a design tool reverse, which has been obtained through the combination of an electro-magnetic simulator of the problem based on the theory of multiple scattering and a stochastic optimization method based on algorítmos genetic. The software was written in Fortran 90 and can run in both Windows and Linux platforms. The effectiveness of the design tool has been demonstrated by generating a series of devices that meet the constraints of proven technology manufacturing and assembling; sheet glass fotónico and technical micro-manipulación respectively. Partners technique micro-manipulación, a new family of optical elements, the so-called "optical scattering elements" (SOE), has been introduced. Specifically, the devices have been designed: lenses, dividers wavelength, waveguide couplers, collimators and photonic cavities, which show promising new features. It has also been shown that it can provide a single device several functionalities using the same method of reverse design. Finally, experimental results have been obtained in the field of dispersion acoustic waves which confirm the high quality of the design tool. Several prototypes of acoustic lenses and dividers wavelength, very similar to SOE designs have been manufactured and the characterization of its acoustic properties has confirmed those prefixed in the design.
