Principal modes in multimode fibers: exploring the crossover from weak to strong mode coupling
Wen Xiong, Philipp Ambichl, Yaron Bromberg +3
We present experimental and numerical studies on principal modes in a multimode fiber with mode coupling. By applying external stress to the fiber and gradually adjusting the stres…
Control of energy density inside disordered medium by coupling to open or closed channels
Raktim Sarma, Alexey Yamilov, Sasha Petrenko +2
We demonstrate experimentally an efficient control of light intensity distribution inside a random scattering system. The adaptive wavefront shaping technique is applied to a silic…
Spatio-temporal Control of Light Transmission through a Multimode Fiber with Strong Mode Coupling
Wen Xiong, Philipp Ambichl, Yaron Bromberg +2
We experimentally generate and characterize the eigenstates of the Wigner-Smith time-delay matrix, called principal modes, in a multimode fiber with strong mode coupling. The uniqu…
