Light and electron-beam induced structural transformations in nanoparticles of polymorphic metals provide a paradigm for achieving resonator-less optical memory functionality with picojoule energy requirements. We demonstrate optical memory function with gallium nanoparticles grown by light-assisted self-assembly at the end face of an optical fiber and show how a nanoparticle can constitute an optical memory bit which can be read and erased by a weak probe beam, and written by a single optical control pulse.
