Rogue Waves are highly unstable waves extremely localized in space and time, appearing from nowhere and disappearing without leaving a trace. The observation of such waves in oceanography has led to increased interest in the physics community where optical rogue waves generated using microstructured fibers are studied for their interactions and the underlying physical phenomena. In the present article, an extremely simple rogue wave generator is proposed, where a hyperbolic secant based temporal profile evolves according to a hyperbolic secant square spatial profile. The derivative of this spatial profile gives the spatial evolution equation, and this is implemented using FPGA. It is seen that a single rogue wave exponentially rising to its peak amplitude at mid time instant and then quickly decaying is formed. The extremely simple signal-oriented design of rogue wave generator, effectively capturing the spatial and temporal propagation properties of such rogue waves, coupled with the potential applications it enables using the generated electrical rogue waves forms the novelty of the present work.
