Double filtering function using two combined Bragg gratings
Résumé
In this paper, we report the realization of a double Bragg gratings (BG) structure based on titanium-diffused optical waveguides in lithium niobate Ti:LiNbO3 by using Focused Ion Beam (FIB) technique. A double filtering function in wavelengths around the bands 1200nm and 1550nm has thereby been achieved
