Abstract: An optical modulator may include an optical wave guide configured to allow a light to pass therethrough, and an optical modulating layer embedded in the optical wave guide and configured to modulate a phase of the light. The optical wave guide may include a first material that has a first lattice constant. The optical modulating layer may include a second material that has a second lattice constant different from the first lattice constant. The phase of the light may be modulated by the optical modulating layer based on a difference between the first lattice constant and the second lattice constant.
