Coherent Perfect Absorption of Arbitrary Wavefronts at an Exceptional Point
Helmut Hörner, Lena Wild, Yevgeny Slobodkin +3
A Coherent Perfect Absorber (CPA) exploits the interferometric nature of light to deposit all of a light field's incident energy into an otherwise weakly absorbing sample. The down…
Imaging and Identification of Single Nanoplastic Particles and Agglomerates
Ambika Shorny, Fritz Steiner, Helmut Hörner +1
Currently the extent of nanoplastic in the environment can only be estimated by extrapolation from the plastic waste that can be detected. To be able to quantify the whole extent o…
Massively degenerate coherent perfect absorber for arbitrary wavefronts
Yevgeny Slobodkin, Gil Weinberg, Helmut Hörner +3
One of the key insights in the emerging field of non-Hermitian photonics is that well-established concepts like the laser can be operated in reverse to realize a 'coherent perfect…
