A method to design gratings in integrated photonics, is presented. The based on a transfer matrix formalism enhanced by Finite Element Method (FEM) parameter calculations. main advantages of the proposed technique are easy use, fast optimization time and versatility approach. Few examples optimized obtain various scattered light field profiles for different applications presented: double-Gaussi...

The RGB signals generated by different cameras are not equal for the same scene. Therefore, cameras are characterized based on a CIE standard colorimetric observer. One method of deriving a colorimetric characterization matrix between camera RGB output signals and CIE XYZ tristimulus values is least squares polynomial modeling. Yet, this involves tedious experiments to obtain a camera transfer ...
