An analytic model of a bonding layer for a fiber Bragg grating (FBG) bonded on a substrate was developed to predict the strain transfer from the substrate to the FBG when the substrate is subjected to ...

We propose a design of grating couplers having low back-reflections on silicon-on-insulator (SOI). The grating trenches are etched asymmetrically on the grating coupler. The asymmetric grating ...
