Wavelength\u2010tunable excitation (660\u2013405\u00a0nm) enables robust, bidirectional polarization reversal through the interaction between the photogenerated charges in MoS\n                    <jats:sub>2<\/jats:sub>\n                    \/CIPS heterostructure and ferroelectric polarization charges in CIPS. Two wavelength\u2010dependent carrier dynamic mechanisms were established specifically for excitations below and above the CIPS bandgap. These mechanisms result in opposite charge accumulation at the interface, leading to opposite polarization switching directions. The device demonstrates high\u2010performance all\u2010optical nonvolatile memory. Furthermore, it emulates all\u2010optical controlled retina\u2010like synaptic plasticity, including paired\u2010pulse facilitation\/inhibition, short\u2010term and long\u2010term potentiation and depression, and learning\u2010forgetting behaviours, with wavelength\u2010selective long\u2010term potentiation and depression enabling neuromorphic image recognition. Additionally, the single device implements reconfigurable all\u2010optical controlled Boolean logic gates.\n
