Abstract Polarization‐sensitive perovskite photodetectors (PSPPDs) have demonstrated great potential for acquiring multidimensional data in remote sensing, security, and optical communication fields. However, requirements of external power supplies polarization systems, slow response, poor long‐term stability restrict PSPPDs’ further development. Herein, a self‐powered PSPPD with buried grating structures induced by ultrafast laser direct writing is designed. Remarkably, detection can be...
Metal halide perovskite has generated significant attention due to its high optical absorption coefficient, the tunability of bandgap, and solution processing properties, all which have led a range applications including solar cells, photodetectors, light-emitting diodes lasers. However, material's application as an modulator for high-energy ultrafast lasers is still limited by slow nonlinear response, low damage threshold inferior stability. Herein, we developed saturable absorber (SA) with...
