Columbia Engineering develops Kerr frequency comb generator

A catalyst for fast processes in physics, biology, chemistry, as well as fields such as communication, navigation, and more are optical frequency combs. Challenges related to these combs have been primarily related to how to make them smaller, more robust, and portable. Within the last decade, chip-based microresonators have been used to produce these combs. However, they rely on larger, expensive, and power-hungry lasers.

Columbia Engineering researchers announced they have built a Kerr frequency comb generator which integrates the laser with the microresonator for the first time. This significantly reduces the system’s size and power requirements.

The researchers were able to collaborate using NYSERNet’s R&E network.
