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…
IQ Photonic Receiver for Coherent Imaging with a Scalable Aperture
Aroutin Khachaturian, Reza Fatemi, Ali Hajimiri
Silicon photonics (SiP) integrated coherent image sensors offer higher sensitivity and improved range-resolution-product compared to direct detection image sensors such as CCD and…
Achieving Full Grating-Lobe-Free Field-of-View with Low-Complexity Co-prime Photonic Beamforming Transceivers
Aroutin Khachaturian, Reza Fatemi, Ali Hajimiri
Integrated photonic active beamforming can significantly reduce the size and cost of coherent imagers for LiDAR and medical imaging applications. In current architectures, the comp…
Three Dimensional Aggregation of Magnetic Particles
Alex Pai, Dimitar Ho, Ali Hajimiri
Magnetic drug delivery is a promising therapeutic because of magnetic fields' ability to permeate unperturbed in human tissue. One of the long-standing challenges in magnetic drug…
