  • Researchers demonstrate a multilevel non-volatile phase shifter memory that is based on the monolithic integration of BaTiO3 thin films and silicon waveguides. By manipulating ferroelectric domains in BaTiO3 with electrical control signals, they achieve analogue and non-volatile optical phase tuning.
