Abstract :
This paper proposes to extend the self-mixing operation to chaotic conditions, using a dually distributed cavity: a distributed feedback (DFB) laser is connected to a 95% reflective fiber Bragg grating (FBG), which acts as a distributed reflector. The FBG is perturbed with static and dynamic strain, changing its reflectivity at the DFB wavelength.
