Nearly 180° Field‐of‐View Metalens for Miniaturized Imaging Systems
Laser &Photonics Reviews, EarlyView.A compact, single‐layer metalens is developed with an ultra‐wide field of view of ≈180 degrees. Utilizing a unique quadratic phase profile, this metalens overcomes traditional issues like axial and color dispersion. It operates across red, green, and blue wavelengths with non‐polarized light, promising enhanced imaging capabilities for integration into

Reinforcement Learning Enabled Nanophotonic Devices
Laser &Photonics Reviews, EarlyView.A reinforcement learning algorithm is used to design photonic devices. The method creates metagratings and grating couplers that efficiently control both the direction and polarization of light. Further, a reinforcement learning approach is used to design in‐plane integrated photonic devices. This approach paves the way for advanced photonic components

Laser &Photonics Reviews, EarlyView.Manipulating the ultranarrow linewidth spectral features of quasi bound states in the continuum is challenging. A metasurface supporting linear‐to‐linear cross‐polarization coupling efficiency surpassing 25% is proposed to address the issue. Less than 100 nm linewidth is achieved, enabling the device to be applied to wavelength‐selective polarization ...

Laser &Photonics Reviews, EarlyView.In randomly distributed Cu2O octahedron particles on a glass substrate, the absence of particles in certain areas generates a distinct “void‐particle induced interference” phenomenon. This effect results in notable reflection and transmission dichroism, characterized by two reflection peaks within the visible spectrum, but only a single transmission ...
