Multi-wavelength polarisation imaging with inverse designed metasurfaces
Sarah E. Dean, Neuton Li, Josephine Munro +7
Multispectral polarisation imaging has a broad range of applications, from biological cell imaging to agricultural remote surveying. For such applications, especially involving lig…
Metasurface-enabled small-satellite polarisation imaging
Sarah E. Dean, Josephine Munro, Neuton Li +3
Polarisation imaging is used to distinguish objects and surface characteristics that are otherwise not visible with black-and-white or colour imaging. Full-Stokes polarisation imag…
Angle multifunctional dichroism in metasurfaces
Neuton Li, Jihua Zhang, Dragomir Neshev +1
We demonstrate metasurfaces with strong polarization dichroism that depends on the angle of incidence. We present original designs obtained through topology optimization that selec…
Single-shot characterization of photon indistinguishability with dielectric metasurfaces
Jihua Zhang, Jinyong Ma, Neuton Li +2
Characterizing the indistinguishability of photons is a key task in quantum photonics, underpinning the tuning and stabilization of the photon sources and thereby increasing the ac…
Inverse Design of Nonlinear Metasurfaces for Sum Frequency Generation
Neuton Li, Jihua Zhang, Dragomir N. Neshev +1
Sum frequency generation (SFG) has multiple applications, from optical sources to imaging, where efficient conversion requires either long interaction distances or large field conc…
