Heterogeneous III-V/Si (de-) interleaver filters with non-volatile memristive functionality

An optical filter, comprising:

• a first waveguide formed on a substrate;
• and
• a phase shift mechanism coupled to the first waveguide, the phase shift mechanism comprising:
• a semiconductor material layer bonded to a length of the first waveguide;
• and
• a filamentation layer formed between the first waveguide and the semiconductor material,
• wherein the filamentation layer causes a non-volatile change in a refractive index of the first waveguide.

A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform a method comprising, comprising:

• tuning a phase shift of a first waveguide from an initial phase to a non-volatile phase shift by applying a first voltage bias to a metal-oxide-semiconductor capacitor (MOSCAP) coupled to the first waveguide;
• filtering an input optical signal based on the non-volatile phase shift;
• and
• tuning the phase shift of the first waveguide to the initial phase shift by applying a second voltage bias to the MOSCAP, the second voltage bias having a polarity that is opposite of the first voltage bias.
