Deep learning of ultrafast pulses with a multimode fiber
Wen Xiong, Brandon Redding, Shai Gertler +3
Characterizing ultrashort optical pulses has always been a critical but difficult task, which has a broad range of applications. We propose and demonstrate a self-referenced method…
Multimode fiber based single-shot full-field measurement of optical pulses
Wen Xiong, Shai Gertler, Hasan Yilmaz +1
Multimode fibers are widely explored for optical communication, imaging and sensing applications. The interference of fiber guided modes generates a speckle pattern, which has been…
Spatio-temporal correlations in multimode fibers for pulse delivery
Wen Xiong, Chia Wei Hsu, Hui Cao
Long-range speckle correlations play an essential role in wave transport through disordered media, but have rarely been studied in other complex systems. Here we discover spatio-te…
Statistical Description of Transport in Multimode Fibers with Mode-Dependent Loss
P. Chiarawongse, H. Li, W. Xiong +3
We analyze coherent wave transport in a new physical setting associated with multimode wave systems where reflection is completely suppressed and mode-dependent losses together wit…
Complete Polarization Control in Multimode Fibers with Polarization and Mode Coupling
Wen Xiong, Chia Wei Hsu, Yaron Bromberg +3
Multimode optical fibers have seen increasing applications in communication, imaging, high-power lasers and amplifiers. However, inherent imperfections and environmental perturbati…
Super- and Anti-Principal Modes in Multi-Mode Waveguides
Philipp Ambichl, Wen Xiong, Yaron Bromberg +3
We introduce a new type of states for light in multimode waveguides featuring strongly enhanced or reduced spectral correlations. Based on the experimentally measured multi-spectra…
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…
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…
Topological defect lasers
Sebastian Knitter, Seng Fatt Liew, Wen Xiong +3
We demonstrate topological defect lasers in a GaAs membrane with embedded InAs quantum dots. By introducing a disclination to a square-lattice of elliptical air holes, we obtain sp…
Photonic crystals with topological defects
Seng Fatt Liew, Sebastian Knitter, Wen Xiong +1
We introduce topological defect to a square lattice of elliptical cylinders. Despite the broken translational symmetry, the long-range positional order of the cylinders leads to re…
