A representation of resonant reflection based on phenomenological parameters enables the designer to achieve the synthesis of the mirrored waveguide grating structure exhibiting the desired temporal pulse shape. The example of a temporal beam splitter under fabrication is presented. Experimental results will be presented at the conference. %G English %L ujm-00161517 %U https://ujm.hal.science/ujm-00161517 %~ UNIV-ST-ETIENNE %~ IOGS %~ CNRS %~ LAHC %~ PARISTECH %~ UDL
