Experimental demonstration of photonic phase correctors based on grating coupler arrays and thermo-optic shifters
Momen Diab, Ross Cheriton, Jacob Taylor +9
In ground-based astronomy, the ability to couple light into single-mode fibers (SMFs) is limited by atmospheric turbulence, which prohibits the use of many astrophotonic instrument…
End-to-end simulations of photonic phase correctors for adaptive optics systems
Dhwanil Patel, Momen Diab, Ross Cheriton +8
Optical beams and starlight distorted by atmospheric turbulence can be corrected with adaptive optics systems to enable efficient coupling into single-mode fibers. Deformable mirro…
Extending the spectral operation of multimode and polarization-independent power splitters through subwavelength nanotechnology
Raquel Fernández de Cabo, David González-Andrade, Pavel Cheben +1
Power splitters play a crucial role in virtually all photonic circuits, enabling precise control of on-chip signal distribution. However, state-of-the-art solutions typically prese…
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…
Optical wavefront phase-tilt measurement using Si-photonic waveguide grating couplers
Siegfried Janz, Dan-Xia Xu, Yuri Grinberg +5
