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…
Optical wavefront phase-tilt measurement using Si-photonic waveguide grating couplers
Siegfried Janz, Dan-Xia Xu, Yuri Grinberg +5
Silicon photonic wavefront phase-tilt sensors for wavefront monitoring using surface coupling grating arrays are demonstrated. The first design employs the intrinsic angle dependen…
Genetic optimization of Brillouin scattering gain in subwavelength-structured silicon membrane waveguides
Paula Nuño Ruano, Jianhao Zhang, Xavier Le Roux +6
On-chip Brillouin optomechanics has great potential for applications in communications, sensing, and quantum technologies. Tight confinement of near-infrared photons and gigahertz…
