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…
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…
Experimental characterization of an ultra-broadband dual-mode symmetric Y-junction based on metamaterial waveguides
Raquel Fernández de Cabo, Jaime Vilas, Pavel Cheben +2
Silicon photonic integrated circuits routinely require 3-dB optical power dividers with minimal losses, small footprints, ultra-wide bandwidths, and relaxed manufacturing tolerance…
Highly efficient ultra-broad beam silicon nanophotonic antenna based on near-field phase engineering
Shahrzad Khajavi, Daniele Melati, Pavel Cheben +3
Optical antennas are a fundamental element in optical phased arrays (OPA) and free-space optical interconnects. An outstanding challenge in optical antenna design lies in achieving…
Mid-infrared Fourier-transform spectrometer based on metamaterial lateral cladding suspended silicon waveguides
Thi Thuy Duong Dinh, Xavier Le Roux, Natnicha Koompai +9
Integrated mid-infrared micro-spectrometers have a great potential for applications in environmental monitoring and space exploration. Silicon-on-insulator (SOI) is a promising pla…
