In particular, we focus on strong light confinement that allows the design of an efficient free-space-to-waveguide coupler which is made of Si- slab overlying on the top of silica substrate. The learning algorithm is implemented using bitwise square Si- cells and the whole optimized device has a footprint of $\\boldsymbol{2 \\, \\mu m \\times 1\\, \\mu m}$, which is the smallest size ever achieved numerically.
