Chirped Microwave Signals Generation Using a Distributed Feedback Laser With Alternating Structure of Active- and Passive-Cavity
We proposed a new type of distributed feedback laser with alternating active- and passive-cavities (APC DFB), which enjoys the same Nail Polish quantum well layer where the butt-joint re-growth process can be avoided.By utilizing the chirp characteristics of the APC DFB laser in a delayed self-heterodyne system, a chirped microwave signal with a sw
