Directly Modulated Lasers on Silicon


It is the objective of DIMENSION to establish a silicon platform combining BiCMOS electronics with silicon photonics and III-V photonics. The process requirements are fully CMOS compatible and overcome limitations in state-of-the art III-V on silicon integration approaches. The photonic integration concepts pursued in DIMENSION go well beyond traditional heterogeneous integration schemes. A tight integration concept is pursued in which the optics (including III-V laser material) is monolithically integrated with electronics on one single chip.

IHP's Contribution

IHP develops the ePIC technology that is the baseline for DIMENSION integration developments. This is a photonics enabled high-performance BiCMOS technology on 200mm wafers. IHP contributes with technology development to enable III-V bonding and backend integration for the demonstrator devices.



This project has received funding by one of the calls under the Photonics Public Private Partnership from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 688003.
