Large-Scale Crosstalk-Corrected Thermo-Optic Phase Shifter Arrays in Silicon Photonics
Volkan Gurses, Reza Fatemi, Aroutin Khachaturian +1
We introduce a thermo-optic phase shifter (TOPS) array architecture with independent phase control of each phase shifter for large-scale and high-density photonic integrated circui…

Discretization of Annular-Ring Diffraction Pattern for Large-Scale Photonics Beamforming
Aroutin Khachaturian, Reza Fatemi, Artsroun Darbinian +1
A solid-state active beamformer based on the annular-ring diffraction pattern is proposed for an integrated photonic platform. Such a circularly symmetric annular-ring aperture ach…
