Color-Filter-Free Image Sensor Using CsPbBr₃ Quantum-Dot-Based Tamm Plasmon Photodetector for Photonic Synapse Facial Recognition.

ABSTRACT: This study demonstrates that optical absorption of the CsPbBr₃ quantum dots can be significantly enhanced through monolithic integration with the Tamm plasmon (TP) structure. This integration enables the resulting TP photodetector to achieve a higher photocurrent and a more linear power dependence compared to the reference device with a nonresonant configuration. The enhancement is confined to the designed resonant energy, while photons with off-resonance energies are fully reflected, making the TP photodetector an ideal candidate for compact and efficient image sensors, eliminating the need for additional filters or bulky microlenses for color discrimination or photon collection. Furthermore, the photocurrent generated by the TP photodetector can be regulated by varying light p
