The use of transfer printing technology to integrate active silicon photonic components on a silicon nitride waveguide circuit is proposed. Alignment tolerant coupling schemes were designed using full vectorial simulations. Adiabatic taper structures allow 80% coupling efficiency at 1 μm misalignment for the O-band and 97% for the C-band. Compact directional coupler structures allow 80% efficiency for 1 μm misalignment for both bands. We present first transfer-printing technology results. This includes the release, picking and printing of silicon coupons from an SOI source wafer to a silicon target wafer. The impact of stress in the silicon membrane on the transfer printing process is assessed.
