Title: Optical Frequency Combs on Photonic Integrated Circuits
Abstract
We will present our advances in the development of photonic integrated circuits (PICs) for the generation of optical frequency combs, aiming at the optical distribution of frequency standards and calibration signals. Photonic techniques allow the generation of high quality signals through a number of techniques. We will describe here those for the generation of comb lines, which benefit over electronic techniques in the possibility of using optical fiber to transport signal with very low propagation loss. We will focus on solutions for low fundamental frequencies (< 10 GHz) reporting integrated long cavity mode locked ring structure with a low repetition rate at 2.7 GHz under passive and hybrid regimes. The device exhibits a very narrow RF linewidth of the beat note of few KHz.

Guillermo Carpintero is Associate Professor at the Electronics Department at Universidad Carlos III de Madrid (UC3M). He is leading research on Photonic Integrated Circuits, exploring the development of photonic light engines (photonic systems on a chip) for various fields of application. The most important area of application is integrated microwave photonics, reaching into the millimeter and Terahertz ranges. Integrated optical frequency combs are a step forward into coherent integrated microwave photonic systems.
