Efficiently transducing microwave signals into optical signals is one of the major demands in modem telecommunication. Electro-optical crystals hosting optical whispering gallery modes incorporated in a properly designed microwave cavity emerge as a promising candidate towards much more efficient microwave-to-light transducer [1, 2]. Here, we propose to use a ferroelectric crystal close to its paraelectric-ferroelectric...
The exploration of the interaction of light with spin waves in ferromagnets within an optical cavity might lead to new chiral photonic devices and be a stepping stone towards the coherent optical manipulation of magnons in the quantum regime [1]. The developments made so far in cavity optomagnonics have been focused on the fundamental magnetostatic mode of an yttrium iron garnet (YIG) sphere, so-called...
We explore the vectorial optomechanical interaction between a nanowire and a focused beam of light. The nanowire is sensitive to the topological variations of the focused laser force field which dramatically modify the phenomenology of the dynamical backaction. The non-conservative topology of the optomechanical interaction is responsible for a novel canonical signature of strong coupling between...

Most of the optomechanical studies [1] have so far been restricted to objects with sizes much larger than the optical wavelength. Sensitive nano-optomechanical coupling has also been evidenced, but with wavelength size objects which were incorporated into advanced optical microcavity designs. We report a new of ultra-sensitive nano-optomechanical system that breaks these barriers, and enables unprecedentedly...
We investigate the nano-optomechanical properties between a nanowire and a focused beam of light. Based on such a system, we report unprecedently sensitive vectorial detection of nanomechanical motion using SiC nanowires and Carbon nanotubes.
