Unitary control of partially coherent waves. II. Transmission or reflection
Cheng Guo, Shanhui Fan
Coherent control of wave transmission and reflection is crucial for applications in communication, imaging, and sensing. However, many practical scenarios involve partially coheren…
Unitary control of partially coherent waves. I. Absorption
Cheng Guo, Shanhui Fan
The coherent control of wave absorption has important applications in areas such as energy harvesting, imaging, and sensing. However, most practical scenarios involve the absorptio…
Topological winding guaranteed coherent orthogonal scattering
Cheng Guo, Shanhui Fan
Coherent control has enabled various novel phenomena in wave scattering. We introduce an effect called coherent orthogonal scattering, where the output wave becomes orthogonal to t…
Topological nature of non-Hermitian degenerate bands in structural parameter space
Olivia Y. Long, Cheng Guo, Shanhui Fan
In photonics, band degeneracies at high-symmetry points in wavevector space have been shown to exhibit rich physical phenomena. However, obtaining degenerate bands away from such p…
Polarization-independent isotropic nonlocal metasurfaces with wavelength-controlled functionality
Olivia Y. Long, Cheng Guo, Weiliang Jin +1
Flat optics has demonstrated great advances in miniaturizing conventional, bulky optical elements due to the recent developments in metasurface design. Specific applications of suc…
