Reservoir Computing with All‐Optical Non‐Fading Memory in a Self‐Pulsing Microresonator Network

Advanced Optical Materials, EarlyView.
A photonic reservoir computing architecture based on 64 coupled silicon microring resonators is used to achieve non‐fading memory, demonstrating robust multi‐timescale signal processing capabilities. The passive photonic network exhibits nonlinear dynamics and multistability, facilitating extended information retention exceeding tens of microseconds ...

Femtosecond Direct Laser Writing of Conductive and Electrically Switchable PEDOT:PSS Optical Nanostructures

Advanced Optical Materials, EarlyView.
Commercial femtosecond direct laser writing (Nanoscribe GT) is utilized to fabricate electrically switchable PEDOT:PSS nanostructures on ITO‐coated glass substrates, as well as underneath and on top of 3D‐printed structures and demonstrates beam‐switching at 1550 nm. Abstract Microscale three‐dimensional (3D)‐printing, with its remarkable precision and

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‐
