Fundamental limits on nanophotonic devices: a complement to inverse design

Sean Molesky, Pengning Chao, Jewel Mohajan, Alejandro Rodriguez

Princeton University, United States of America

Development of general-purpose electromagnetic solvers have been principally driven by the tantalizing possibility of accessing the full wave physics contained in Maxwell’s equations. Such developments have in turn raised questions pertaining to the underlying physical limitations of optical devices. In this talk, we present an overview of recently developed general-purpose optimization techniques aimed at understanding the interplay of fundamental physics and optimal device performance. We provide examples of recent applications that establish fundamental limits to light scattering, light–matter interactions, fluctuation phenomena, optical transformations, and communication.

Spin glasses (SGs) are paradigmatic physical models whose dynamics computation is nondetermistic polynomial-time hard. Here we report on a recent implementation of the optical simulation of an SG, exploiting the N segments of a wavefront-shaping device to play the role of the spin variables, combining the interference downstream of a scattering material to realize the random couplings between the spins. In the optical SG, where interaction terms are realized simultaneously when the independent light rays interfere on the detector’s surface, we demosntrate a speedup, with respect to purely in-silico simulations, scaling with N.

Engineering lensless imaging systems based on scalar random fields

Yuyao Chen, Luca Dal Negro

Boston University, United States of America

We present a novel multispectral lensless imaging concept based on hyperuniform phase plates

(HPPs). In particular, we design point-spread-functions (PSFs) from scalar random fields obtained by solving nonlinear reaction-diffusion equations with hyperuniform solutions. We demonstrate isotropic modulated

transfer functions and compare against state-of-the-art lensless systems with contour-PSFs based on the Perlin

noise. Finally, we fabricate the proposed HPPs within a four-level phase discretization approach using scalable

photolithography and demonstrate their multispectral imaging capabilities using high-fidelity computational

imaging. The extension of the proposed concepts to the infrared region is also discussed.

Polymeric complex photonic systems and their application in Information Communication Technology

Complex photonic systems own a large structural information content that can be probed and measured by coherent light. We experimentally demonstrate how to extract the maximal entropy from disordered polymeric systems, what the limitations are and how to overcome such limits via a fine and local engineering of the polymeric material.
