“…On one hand, multimode fibers exhibit low transmission losses, large core diameters, high numerical apertures (NAs), and the ability to handle high power. These characteristics render them popular in applications like spectrometers [22], endoscopy [23], holography [24], high-power light delivery [25], and even light detection and ranging (LiDAR) systems [20,21]. On the other hand, in these applications, speckle is readily induced due to the mutual interference between different modes in the fiber, subsequently leading to adverse effects.…”

We present a technique that utilizes cascaded resonant cylindrical piezoelectric ceramics and multimode optical fibers wound around them to effectively mitigate laser speckle. By precisely driving the ceramics at their resonant frequencies and inducing comprehensive mode scrambling within the multimode fiber, we achieve a remarkable speckle suppression efficiency of up to 94%. To the best of our knowledge, this sets a new benchmark among various methods aimed at suppressing the speckle of a coherent light. Our study thoroughly explores variables influencing efficiency, including the cascading number of piezoelectric ceramics, driving voltage, fiber core diameter, and more. This method has significant promise for diverse applications that require efficient and fast control of speckle contrast.
