Abstract :
We have demonstrated a miniature microwave chirp generator using a three-section dual-wavelength DFB laser. Because the saturable absorption section, which performs high-speed photo detection, is made on the same chip, no external optical coupling is necessary. The entire structure is integrated and self-consistent, it will find applications in future wireless and space-borne communications
