"optical microresonators struggle with uncontrolled backward signals/ network crosstalk... overcome integrating microheaters adjusting internal light paths enabling directional firing/ electrically controlled back-action mimicking biological neural regulation... tunable electric current for silent, excitable, hypersensitive functional states... standard silicon process fabrication... eliminates need for extra synaptic components between neurons... scalable neuromorphic photonic computing"
