Abstract
Systems and methods are provided for optical devices with integrated memristor behavior adapted for non-volatile retention of phase tuning. Examples include an optical filter having a first waveguide formed on a substrate and a phase shift mechanism coupled to the first waveguide. The phase shift mechanism comprises a semiconductor material layer bonded the first waveguide, and a filamentation layer formed between the first waveguide and the semiconductor material based on applying an electric field to the phase shift mechanism. The filamentation layer causes a non-volatile change in a refractive index of the first waveguide, that provides for phase detuning.
