Abstract
An electro-optic device including a first waveguide, a second waveguide, and electrodes is described. The first waveguide includes a first thin film lithium-containing (TFLC) electro-optic material and carries a first optical signal. The second waveguide includes a second TFLC electro-optic material and carries a second optical signal. The electrodes include a differential electrode pair proximate to a portion of the first waveguide and to a portion of the second waveguide. The differential electrode pair is configured to provide a first modulation to the first optical signal and a second modulation to the second optical signal. A first magnitude of the first modulation is different from a second magnitude of the second modulation such that the electro-optic device has an engineered chirp.
