ABSTRACT:
There is provided in one of the embodiments of the disclosure a lithium niobate modulator structure for mitigating DC bias drift comprising a highly doped semiconductor layer patterned above an optical waveguide having one or more DC sections and an RF section, wherein a metal layer or contact is in contact with a portion of the semiconductor layer and a buffer layer is deposited in the RF section. There is provided in another embodiment of the disclosure a method for making a lithium niobate electro-optical modulator for mitigation of DC bias drift.
