NanoPhOtonic devices applying SElf-assembled colloIDs for novel ON-chip light sources (POSEIDON)
The ground-breaking aim of POSEIDON is to develop a radically new bottom-up approach towards multi-scale, on chip self-assembly of active colloids based on low cost colloid technology. For the first time this encompasses the entire process chain of computer-aided design, controlled synthesis, hierarchical assembly, optoelectronic integration and device fabrication. By controlling and designing self-assembly processes directly on a device, addressing length scales from nm to 100’s of μm simultaneously, the POSEIDON approach allows to fabricate functional nanophotonic components with 3D, single-nm resolution integrated into complex PICs. The ambitious goal of POSEIDON is to develop electrically pumped light sources which can be monolithically integrated into the back end of CMOS chips. This breakthrough overcomes the limitations of top-down PIC fabrication and tears down the massive cost and complexity barriers initially mentioned.
