Abstract:An essential metric to quantify the stability of a laser is its frequency noise (FN). This metric yields information on the linewidth and on noise components which limit its usage for high precision purposes such as coherent communication. Its experimental determination relies on challenging optical phase measurements, for which dedicated commercial instruments have been developed. In contrast, this work presents a simple and cost-effective method for extracting FN features employing a delayed self-heterodyne … Show more
