Enhanced Nonlinearity of Epsilon-Near-Zero Indium Tin Oxide Nanolayers with Tamm Plasmon-Polariton States

Tornike Shubitidze, Wesley A. Britton, Luca Dal Negro

Recently, materials with vanishingly small permittivity, known as epsilon-near-zero (ENZ) media, emerged as promising candidates to achieve nonlinear optical effects of unprecedent…

Inverse design of ultracompact multi-focal optical devices by diffractive neural networks

Yuyao Chen, Yilin Zhu, Wesley A. Britton +1

We propose an efficient inverse design approach for multifunctional optical elements based on adaptive deep diffractive neural networks (a-DNNs). Specifically, we introduce a-D…
