摘要

Self-governing synchronization of oscillators requires both nonlinear behavior and correct connectivity. All lasers are nonlinear oscillators. Fiber lasers are a particularly ideal testbed for self-organization because the huge difference between unsaturated and saturated gain allows extremely nonlinear behaviors and because fibers have the flexibility to be connected in almost any way one might desire. There are two practical consequences of looking at laser coupling from this vantage point rather than the more traditional supermode approaches. First, we are freed from the requirement that lasers must be identical lengths in order to lock, or that only modes of the individual lasers that happen to coincide in frequency will lock. We stop looking at lasers as linear resonators with gain, and accept that they can self-tune as needed in response to interactions with other lasers via nonlinear mechanisms such as saturation. Second we can start to focus on the architecture of the connectivity rather than the degree of coupling.
