Strong Cavity-Optomechanical Transduction of Nanopillar Motion

Nanomechanical resonators can serve as ultrasensitive,miniaturized force probes. While vertical structures such as nanopillarsare ideal for this purpose, transducing their motion is challenging. Pillar-based photonic crystals (PhCs) offer a potential solution by integratingoptical transduction withi...

description Nanomechanical resonators can serve as ultrasensitive,miniaturized force probes. While vertical structures such as nanopillarsare ideal for this purpose, transducing their motion is challenging. Pillar-based photonic crystals (PhCs) offer a potential solution by integratingoptical transduction within the pillars. However, achieving high-qualityPhCs is hindered by inefficient vertical light confinement. Here, wepresent a full-silicon photonic crystal cavity based on nanopillars as aplatform for applications in force sensing and biosensing areas. Its unit cellconsists of a silicon pillar with a larger diameter at its top portion than atthe bottom, which allows vertical light confinement and an energy bandgap in the near-infrared range for transverse-magnetic polarization. Weexperimentally demonstrate optical cavities with Q factors exceeding 1e3,constructed by inserting a defect within a periodic arrangement of thistype of pillars. Each nanopillar naturally behaves as a nanomechanicalcantilever, making the fabricated geometries excellent optomechanical (OM) photonic crystal cavities in which the mechanicalmotion of each nanopillar composing the cavity can be optically transduced. These geometries display enhanced mechanicalproperties, cost-effectiveness, integration possibilities, and scalability. They also present an alternative in front of the widelyused suspended Si beam OM cavities made on silicon-on-insulator substrates.
