Abstract

A semiconductor device includes a silicon substrate having a first region and a second region. The semiconductor device includes a silicon lens formed in the first region and along a surface of the silicon substrate on a first side of the silicon substrate. The semiconductor device includes a photonic die disposed in the first region and on a second side of the silicon substrate, the second side being opposite to the first side. The semiconductor device includes a waveguide disposed on the second side of the silicon substrate and having a grating coupler.
