Boundary-dominated optomechanics in silicon metamaterial membranes
David González-Andrade, Paula Nuño Ruano, Jianhao Zhang +10
Stimulated Brillouin scattering in integrated photonic waveguides enables coherent coupling between optical photons and gigahertz acoustic phonons, providing a powerful mechanism f…
Stimulated Forward Brillouin Scattering in Subwavelength Silicon Membranes
Paula Nuño Ruano, Jianhao Zhang, David González-Andrade +6
Brillouin scattering enables efficient and coherent conversion between optical photons and gigahertz-frequency phonons. Integrated circuits that harness this nonlinear interaction…
Perfectly vertical silicon metamaterial grating couplers with large segmentation periods up to 650 nm
Jianhao Zhang, Daniele Melati, Yuri Grinberg +7
Perfectly vertical grating couplers leveraging metamaterials can achieve both high coupling efficiency and minimal back reflection. The fabricability of these designs, with segment…
Shaping the modal confinement in silicon nanophotonic waveguides through dual-metamaterial engineering
T. T. D. Dinh, X. Le Roux, J. Zhang +8
Flexible control of the modal confinement in silicon photonic waveguides is an appealing feature for many applications, including sensing and hybrid integration of active materials…
