Overall results of the project

The HELIOS project was a large and successful project in silicon photonics.

The development of building blocks led to results exceeding the original specifications and moreover positioning the laboratories at the leading edge of the state of the art in the field. Even if it has been challenging to assemble these buildings blocks to fabricate demonstrators as the technology was more complex, advanced transceivers have been obtained. Three different ways of integration the photonic devices with electronic devices on a wafer to wafer basis were pushed with some success. With the work on innovative devices, amorphous silicon modulator exhibited performances far beyond the original expectations. Even if lasing with Si nanocrystals has not been achieved, guided electroluminescence from slot waveguides and micro-ring resonators has been observed. CMOS-compatible 2.5D III-V/Si VCSELs were highly-efficient optically-pumped and lasing with electrical pumping will be soon demonstrated. Moreover experimental demonstration of optical coupling of these VCSEL with silicon micro-guides has been achieved.
