Enabling low Threshold Laser Through an Asymmetric Tetramer Metasurface Harnessing Polarization‐Independent Quasi‐BICs

Advanced Optical Materials, EarlyView.
Light impinging from the left on a metasurface composed by active material. The metasurface shows asymmetric configuration through the non‐uniform presence of holes. The forming quasi‐BICs modes are exploited for lasing purposes. Abstract It is proposed and numerically demonstrated a novel strategy to achieve lasing generation from a dual‐band symmetry‐

Unidirectional Focusing of Light Using Structured Diffractive Surfaces

Advanced Optical Materials, EarlyView.
This study presents a reciprocal diffractive unidirectional focusing design based on linear and isotropic layers. A set of cascaded diffractive layers is designed using deep learning to achieve efficient forward light focusing while suppressing backward propagation across various illumination angles.
