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…
