Optical frequency comb generation in integrated lithium niobate devices

A device comprising:

• a substrate;
• a resonator comprising an electro-optic material, the resonator disposed on the substrate;
• electrodes positioned along the resonator with at least a portion of the resonator disposed between the electrodes, the electrodes adapted to modulate the refractive index of the resonator;
• a pump laser optically coupled to the resonator, wherein
• the resonator is adapted to emit an electro-optical frequency comb when receiving a pump mode from the pump laser and when the electrodes are driven at a frequency, the frequency being an integer multiple of a free-spectral-range of the resonator.
