Topological light-trapping on a dislocation [PDF]
Nature Communications, 2018 Although topological confinement of waves to the edges is common, lower-dimensional wave confinement is scarce. Here, Li et al. demonstrate that concurrent wavevector and real-space topology can lead to a topologically protected zero-dimensional cavity ...

Semiconductor-nanoantenna-assisted solar absorber for ultra-broadband light trapping [PDF]
Nanoscale Research Letters, 2020 Light trapping is an important performance of ultra-thin solar cells because it cannot only increase the optical absorption in the photoactive region but it also allows for the efficient absorption with very little materials.

Light Trapping with Silicon Light Funnel Arrays. [PDF]
Materials (Basel), 2018 Silicon light funnels are three-dimensional subwavelength structures in the shape of inverted cones with respect to the incoming illumination. Light funnel arrays can serve as an efficient absorbing layers on account of their light trapping capabilities associated with the presence of high density complex Mie modes.
