WebThe two common methods for getting light in and out of an integrated photonic chip are via grating couplers or edge couplers. While grating couplers provide a non-destructive solution for coupling light in and out from any location on the chip, their bandwidth can be limited due to dispersive operating principle of grating couplers. WebThe angular distribution of reflection and transmission is only calculated for directions corresponding to the grating orders of the periodic structure. As long as the period is large enough, this provides enough angular resolution.
