Diagonalizing an optical coherence matrix via on-chip Stokes tomography
Amin Hashemi, Abbas Shiri, Bahaa E. A. Saleh +2
Structured coherence -- partially coherent light spanned by a finite number of modes -- is emerging as a powerful tool in optical communications, computation, cryptography, and spe…
On-chip measurement of the modal Stokes-Gell-Mann parameters for partially coherent three-mode light
Amin Hashemi, Abbas Shiri, Bahaa E. A. Saleh +2
The Stokes parameters are three real parameters that completely characterize partially coherent optical fields spanned by two modes -- whether a pair of polarization or spatial mod…
Incoherence-assisted mode excitation in non-Hermitian resonant systems
Amin Hashemi, Vinzenz Zimmermann, Armando Perez-Leija +1
We introduce and experimentally demonstrate an approach for selective mode excitation in non-Hermitian resonant systems using incoherent light. This method eliminates the need for…
On-chip control of the coherence matrix of four-mode partially coherent light: rank, entropy, and modal Stokes parameters
Amin Hashemi, Abbas Shiri, Bahaa E. A. Saleh +2
Partially coherent light offers salutary capabilities in optical information processing that cannot be matched by coherent light. To date, this `coherence advantage' has been confi…
Programmable on-chip synthesis and reconstruction of partially coherent two-mode optical fields
Amin Hashemi, Abbas Shiri, Bahaa E. A. Saleh +2
Partially coherent light is typically studied in the context of freely propagating continuous fields. Recent developments have indicated the existence of a `coherence advantage' in…
Machine-learning-enabled characterization of individual ring resonators in integrated photonic lattices
Elizabeth Louis Pereira, Amin Hashemi, Faluke Aikebaier +3
Accurately determining the underlying physical parameters of individual elements in integrated photonics is increasingly difficult as device architectures become more complex. Infe…
Non-Hermitian topological filters
Vinzenz Zimmermann, Amin Hashemi, Kurt Busch +2
We introduce a non-Hermitian photonic filter that harnesses dissipation to selectively isolate a desired topological state. In science and engineering, dissipation is often used to…
Observation of non-Hermitian topology from optical loss modulation
Amin Hashemi, Elizabeth Louis Pereira, Hongwei Li +2
Understanding the interplay of non-Hermiticity and topology is crucial given the intrinsic openness of most natural and engineered systems and it has important ramifications in top…
