Non-Hermitian Synthetic Phase Shifter: Topologically-Protected Phase Control via Tunable Losses
Kevin Zelaya, Jonathan Friedman, Hector Rubio +2
Phase shifters are fundamental reconfigurable components in photonic circuits. In conjunction with passive elements, they control light flow and serve as foundational building bloc…
Programmable Space-Frequency Linear Transformations in Photonic Interlacing Architectures
Jonathan Friedman, Kevin Zelaya, Mostafa Honari-Latifpour +1
Programmable photonic circuits are versatile platforms that route light through multiple interference paths using reconfigurable optoelectronic elements to perform complex discrete…
Embedding Matrices in Programmable Photonic Networks with Flexible Depth and Width
Matthew Markowitz, Kevin Zelaya, Mohammad-Ali Miri
We show that programmable photonic circuit architectures composed of alternating mixing layers and active layers offer a high degree of flexibility. This alternating configuration…
Integrated Photonic Programmable Random Matrix Generator with Minimal Active Components
Kevin Zelaya, Mostafa Honari-Latifpour, Mohammad-Ali Miri
Random matrices are fundamental in photonic computing because of their ability to model and enhance complex light interactions and signal processing capabilities. In manipulating c…
Photonic Matrix Multiplier Makes a Direction-Finding Sensor
Kevin Zelaya, Mohammad-Ali Miri
We introduce a photonic integrated circuit solution for the direction-of-arrival estimation in the optical frequency band. The proposed circuit is built on discrete sampling of the…
