Wavelength selection in focusing non-uniform grating couplers: A coupling efficiency curve asymmetry and bandwidth analysis
We report a combined experimental and computational investigation of the multi-wavelength response of a series of focusing non-uniform grating couplers designed on multiple SOI thicknesses interfaced with two different fiber coupling schemes. In particular, we demonstrate either the existence of an...
