This study first demonstrates that the random distributed feedback fiber laser (RDFL) can be implemented for sensing detection by using self-mixing effect as a mechanism. By constructing compact velocimeter based on Er-doped RDFL with integration of laser, element, and transmission platform, we successfully measured minimum detectable intensity 38.65 fW velocity signal, corresponding to 0.55 photons per Doppler cycle, exhibiting ultra-high sensitivity dynamics characteristics. In addition,...
Abstract Optical chaos is an attractive topic due to its unique dynamics and has been widely investigated in external‐cavity lasers. While chaotic behavior hindered by undesired periodicity from external feedback. Although a self‐chaotic micro‐laser based on nonlinear interaction of internal modes can eliminate the periodicity, inevitable characteristic frequency related well‐defined cavity limits improvement performance. By virtue inherent randomness, disordered optical system naturally...
