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…
