What should a linear optical frontend compute? Assessing the role of meta-optics, nonlocality, and coherence in hybrid inference systems
Nicholas Behrens, Yandong Li, Francesco Monticone
Hybrid inference systems that pair an optical frontend with a digital backend offer a route to offload computation to the physical layer. Yet what the optics should compute, and wh…
A Unified Perspective on Causality and One-Sided System Responses in Time and Space Across Physical and Fourier Domains
Mohammadreza Salehi, Francesco Monticone
The principle of causality has long been mathematically associated with the frameworks of Titchmarsh's theorem and the Kramers--Kronig relations. While these relations arise natura…
Maximum Q-factor of planar inductors
Mohamed Ismail Abdelrahman, Matteo Ciabattoni, Francesco Monticone
On-chip inductor design plays a critical role in the advancement of radio-frequency integrated circuits (RFICs). Inductors typically occupy a substantial portion of the chip area a…
Nonlocal Microwave Engineering: Shaping Dispersion Relations and Enabling Frequency-Momentum Transformations via Time-Switched Long-Range Interactions
Matteo Ciabattoni, Francesco Monticone
Nonlocal metamaterials (MTMs) have recently attracted significant attention across different areas of wave physics, owing to their ability to translate long-range interactions amon…
Nonlocal photonic time crystals: Infinite momentum bandgaps with minimal modulation speed and strength
Mohammadreza Salehi, Matteo Ciabattoni, Francesco Monticone
For over a decade, photonic time crystals have promised access to novel and exotic optical phenomena, offering fundamentally new ways to manipulate classical and quantum light. Cen…
The Spatial Complexity of Optical Computing and How to Reduce It
Yandong Li, Francesco Monticone
Similar to algorithms, which consume time and memory to run, hardware requires resources to function. For devices processing physical waves, implementing operations needs sufficien…
