The HOT partners consists of 17 leading academic and industrial partners from across Europe, composed of 13 universities and 4 industries. The collaboration is funded by the EU Horizon 2020 FET-Proactive programme for research and innovation.

Together, we will lay the foundation for a new generation of hybrid devices which exploit a nano- or micro-mechanical oscillator to couple and control the electrical, optical and microwave domains. These devices will enable capabilities such as low phase-noise microwave generation, radiofrequency-to-optical conversion and on-chip microwave and optical isolators. Target domains include medicine (MRI), security (radar and terahertz imaging), timing and navigation, and future quantum technology. To this end HOT will develop processes to fabricate the devices in CMOS foundries to allow the technology to scale according to the demands of the consumer market. While the technology investigated by the HOT consortium lends itself to commercialization, there is rich fundamental physics to be investigated in these systems. HOT seeks to generate non-classical states of mechanical systems, observe self-organization of multi-element systems and demonstrate molecular optomechanics.
