Abstract

Frequency chirp simulations based on rate equation analysis are performed for strongly injection-locked ring lasers for applications in optical communication and rf photonics. Different scenarios are explored and compared, including weak injection of a single ring laser, strong injection of a single ring laser, and strong injection of cascaded ring lasers. Together with previously published results, these simulations confirm that the novel whistle-geometry ring laser scheme can provide, especially when modulation signal is applied to both ring lasers in the cascaded arrangement, a greatly improved performance in terms of modulation response and frequency chirp, and more flexibility in the design of ultrahigh speed transmitters.
