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…
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…
