Popup Arrays for Large Space-Borne Apertures
Oren S. Mizrahi, Austin Fikes, Alan Truong +3
Large apertures in space are critical for high-power and high-bandwidth applications spanning wireless power transfer (WPT) and communication, however progress on this front is stu…
Flexible Phased Array Sheets: A Techno-Economic Analysis
Oren S. Mizrahi, Austin Fikes, Ali Hajimiri
Phased arrays have enabled advances in communications, sensing, imaging, and wireless power transfer. In all these applications, large apertures enable higher power, higher data ra…
A Lightweight Space-based Solar Power Generation and Transmission Satellite
Behrooz Abiri, Manan Arya, Florian Bohn +17
We propose a novel design for a lightweight, high-performance space-based solar power array combined with power beaming capability for operation in geosynchronous orbit and transmi…
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…
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…
Gone with the Wind ON_Mars (GOWON): A Wind-Driven Networked System of Mobile Sensors on Mars
Faranak Davoodi, Ali Hajimiri, Neil Murphy +3
We propose a revolutionary way of studying the sur-face of Mars using a wind-driven network of mobile sensors- Gone with the Wind ON_Mars (GOWON). GOWON is envisioned to be a scala…
