We have designed interlayer grating couplers with single/double metallic reflectors for
Si/SiO_2/SiN multilayer material platform. Out-of-plane diffractive grating couplers separated …

General intelligence involves the integration of many sources of information into a coherent,
adaptive model of the world. To design and construct hardware for general intelligence, we …

We present on-chip intra-and inter-layer grating couplers fabricated on double-layer, single
