IQ Photonic Receiver for Coherent Imaging with a Scalable Aperture

Kavli Affiliate: Ali Hajimiri | First 5 Authors: Aroutin Khachaturian, Reza Fatemi, Ali Hajimiri, , | Summary: 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 CMOS devices. Previous generation of SiP coherent imagers suffer from relative optical phase fluctuations between […]

Achieving Full Grating-Lobe-Free Field-of-View with Low-Complexity Co-prime Photonic Beamforming Transceivers

Kavli Affiliate: Ali Hajimiri | First 5 Authors: Aroutin Khachaturian, Reza Fatemi, Ali Hajimiri, , | Summary: Integrated photonic active beamforming can significantly reduce the size and cost of coherent imagers for LiDAR and medical imaging applications. In current architectures, the complexity of photonic and electronic circuitry linearly increases with the desired imaging resolution. We […]
