Electro-optic frequency combs provide tremendous flexibility and agility while being applicable to a wide range of present problems in physical sensing, quantum science, communications, and dynamic spectroscopy. We have developed novel approaches to comb generation [1], spectral translation [2], and their use to interrogate cavity optomechanical sensors [3]. This very active area of research combines work in instrument development, nanophotonics, and spectroscopy.
