Wavefront shaping simulations with augmented partial factorization
Ho-Chun Lin, Zeyu Wang, Chia Wei Hsu
Wavefront shaping can tailor multipath interference to control multiple scattering of waves in complex optical systems. However, full-wave simulations that capture multiple scatter…
Full transmission of vectorial waves through 3D multiple-scattering media
Ho-Chun Lin, Chia Wei Hsu
A striking prediction from the random matrix theory in mesoscopic physics is the existence of "open channels": waves that can use multipath interference to achieve perfect transmis…
High-efficiency high-NA metalens designed by maximizing the efficiency limit
Shiyu Li, Ho-Chun Lin, Chia Wei Hsu
Theoretical bounds are commonly used to assess the limitations of photonic design. Here we introduce a more active way to use theoretical bounds, integrating them into part of the…
Dynamic gain and frequency comb formation in exceptional-point lasers
Xingwei Gao, Hao He, Scott Sobolewski +2
Exceptional points (EPs) -- singularities in the parameter space of non-Hermitian systems where two nearby eigenmodes coalesce -- feature unique properties with applications such a…
Fast multi-channel inverse design through augmented partial factorization
Shiyu Li, Ho-Chun Lin, Chia Wei Hsu
Computer-automated design and discovery have led to high-performance nanophotonic devices with diverse functionalities. However, massively multi-channel systems such as metasurface…
Transmission efficiency limit for nonlocal metalenses
Shiyu Li, Chia Wei Hsu
The rapidly advancing capabilities in nanophotonic design are enabling complex functionalities limited mainly by physical bounds. The efficiency of transmission is a major consider…
Fast multi-source nanophotonic simulations using augmented partial factorization
Ho-Chun Lin, Zeyu Wang, Chia Wei Hsu
Full-wave simulations are indispensable for nanophotonics and electromagnetics but are severely constrained on large systems, especially multi-channel ones such as disordered media…
Thickness bound for nonlocal wide-field-of-view metalenses
Shiyu Li, Chia Wei Hsu
Metalenses -- flat lenses made with optical metasurfaces -- promise to enable thinner, cheaper, and better imaging systems. Achieving a sufficient angular field of view (FOV) is cr…
Observation of bound states in the continuum embedded in symmetry bandgaps
Alexander Cerjan, Christina Jörg, Sachin Vaidya +5
In the last decade, symmetry-protected bound states in the continuum (BICs) have proven to be an important design principle for creating and enhancing devices reliant upon states w…
