We demonstrate analytical manipulation of self-similar rogue waves in a tapered graded-index nonlinear optical fiber. Our exact analysis leads us to a wide class of tapering profiles and the corresponding gain functions, which are allowed by the dynamical equations governing the tapered graded-index nonlinear fiber. “Rogue waves”, “freak waves” and “killer waves”, refer to giant isolated waves that appear from nowhere, having amplitudes significantly larger than the background waves. Firstly observed in the oceans as extreme water waves, rogue waves (RWs) are ubiquitous in nature and appear in a variety of different contexts such as nonlinear optical systems, Bose-Einstein condensates, microwave cavities, etc. In particular, the study of rogue waves has gained fundamental significance in nonlinear optical fiber systems, because of its potential applications in producing high-intensity optical pulses.
