Capteurs optomécaniques compacts à ultra-haut Q
Recent advances in high-stress silicon nitride membranes have enabled some of the most sensitive room-temperature force and displacement measurements ever demonstrated. These ultrathin membranes combine exceptional mechanical performance with very low optical absorption, making them one of the strongest platforms for cavity optomechanics and precision sensing. However, despite their extraordinary capabilities, such systems have remained largely confined to specialist laboratories because they typically require delicate cavity assembly, demanding optical alignment, and expert operation. COMPACT-Q will translate this frontier research into a compact and deployable sensing technology. Building on my ERC-funded work on extreme-aspect-ratio silicon nitride photonic crystal membranes, record-high-Q nanomechanical structures, and monolithically integrated silicon nitride membranes above distributed Bragg reflectors, the project will develop compact high-Q optomechanical sensors based on self-aligned cavity architectures. This removes a major bottleneck in the field by replacing fragile manual cavity construction with a manufacturable integrated platform. The project will validate the sensing performance of these compact integrated systems, identify the most promising combinations of sensitivity, vacuum packaging, size, and robustness for early applications, and define a clear route toward exploitation. Initial target users include advanced sensor and optomechanics researchers who need validated self-aligned cavity platforms, with longer-term opportunities in inertial sensing, gravimetry, vibration monitoring, and precision instrumentation. By moving one of the world’s best room-temperature sensing platforms out of the lab and toward practical deployment, COMPACT-Q aims to open a new technology class of compact silicon nitride cavity optomechanical sensors with strong commercial and societal potential.
