Brief description of the institution:
ICN2 is a renowned research centre. Its research lines focus on the newly discovered physical and chemical properties that arise from the behaviour of matter at the nanoscale.
The Institute promotes collaboration among scientists from diverse backgrounds (physics, chemistry, biology, and engineering) to develop basic and applied research, while seeking out new ways to interact with local and global industry.
It also offers researchers training in nanotechnology, develops numerous activities to promote and enable the uptake of nanotechnology by industry, and promotes networking among scientists, engineers, technicians, business people, society, and policy makers.
ICN2 was accredited in 2014 as a Severo Ochoa Centre of Excellence and is a founding member of the Barcelona Institute of Science and Technology (BIST). The aim of the Severo Ochoa Program, sponsored by the Spanish Ministry of Economy, Industry and Competitiveness, are to identify and support those Spanish research centres that demonstrate scientific leadership and impact at global level.
Brief description of the Centre/Research Group:
The Phononic and Photonic Nanostructures group (P2N) http://icn2.cat/en/phononicand‐photonic‐nanostructures‐group investigates the interactions between phonons, photons and electrons in nano‐scale condensed matter with a long‐term view to develop new information technology concepts where information processing is achieved with novel or multiple state variables. Experimental research is carried out on nanophononics including nano‐scale thermal transport and opto‐mechanical crystals at the cross roads between nanotechnology and dispersion relation engineering. Research in nanophotonicsis focused on methods to control the exciton‐plasmon coupling targeting enhanced light extraction in light sources, and the optimization of the optical gain of printed polymer based photonic structures. Regarding this proposal, P2N has been working in the application of nanofabrication techniques and phonon engineering to tailor dispersion relations for the control of phonon propagation with applications towards opto‐mechanical devices. Tuning the phonon dispersion relation, (phonon engineering) provides a mean of controlling related properties such as group velocity and, ultimately, phonon propagation. P2N has attained two main breakthroughs in the field of opto‐mechanics. The design of opto‐mechanicalcrystals with specific characteristics, (full phononic bandgap). Also reported an integrated coherent phonon source not based in the back‐action scheme, which allows “phononlasing” in response to an an harmonic modulation of the intracavity radiation pressure force.
The coupling of electromagnetic radiation (photons) to mechanical waves (phonons) is at the heart of solid‐state quantum photonics while phonon transport at different frequencies governs crucial physical phenomena ranging from thermal conductivity to the sensitivity of nano‐electromechanical resonators. To engineer and control the overlap of light with the mechanical vibrations of matter in an efficient manner, we make use of very precisely fabricated nanometre‐scale devices. The electromagnetic field and the mechanical displacement are confined simultaneously within the same small volume thus enhancing their interaction. During this project, we will explore novel designs for optomechanical nanostructures and we will measure their mechanical and photonic properties in the lab. We will make use of ultrafast pump and probe techniques to excite and explore the mechanical eigenmodes of these structures using different strategies. Our main goals are:
1. To explore novel designs for optomechanical structures.
2. To measure mechanical cavity modes with an interferometric pump and probe technique.
3. To measure the lifetimes of the mechanical resonances versus different structural and physical parameters.
