Abstract
We present our work in the area of heterogeneous optical integration, where separately manufactured electronic components are assembled on to an active silicon photonics interposer to form a higher-level component. This process allows for the integration of components independently designed and optimized from several different technology and foundry platforms onto a common interposer. Heterogeneous integration is essential for manufacturing higher speed and performance components. Higher levels of integration also allow for closer placement of devices which minimizes the parasitic power consumed to compensate for the frequency dependent losses in the interconnect traces.
