   Abstract:
   A great deal of research to date has focused upon the implementation of polymer optical waveguides with standard electrical interconnection substrates, and there have been demonstrations of polymer waveguides addressing photodetectors (PDs) fabricated in Si and GaAs substrates. This paper describes the heterogeneous integration of independently optimized polymer waveguides, embedded thin film InGaAs PDs operating at a wavelength of 1300 nm, and a standard Si substrate; thus using a different material for each of the three components in the embedded optical waveguide interconnection. Finally, an integrated circuit is attached to the electrical interconnection substrate and wire bonded to the embedded PD. This work represents steps toward chip to chip embedded optical interconnections integrated with electrical interface circuitry
