Mode decomposition for multicore fibers based on far-field intensity measurements Open
We present a mode decomposition method for multicore fibers (MCFs) that is based on intensity measurements in the far-field. Mode decomposition of several homemade multicore fibers is demonstrated in the far-field with low residual errors.…

Sub-nanosecond all-optically reconfigurable photonics in optical fibres Open
We introduce a novel all-optical platform in multimode and multicore fibres. By using a low-power probe beam and a high-power counter-propagating control beam, we achieve advanced and dynamic control over light propagation within the fibre…

Subwavelength and broadband on-chip mode splitting with shifted junctions Open
We design and fabricate a sub-wavelength on-chip mode splitter based on the implementation of a shifted junction between a single-mode waveguide and a multimode waveguide. A proper choice of the device parameters enables to split the input…

Observation of Light Self-Organization and Mode Attraction in a Multimode Optical Fiber Open
We present the first-ever quantitative analysis of mode attraction in a multimode fiber with a counter-propagative setup, as well as an overview of novel self-organization processes.

Multicore fibers: a novel platform for a robust and reconfigurable self-organization of light Open
We report on novel dynamics of light self-organization based on the interaction amongst forward and backward supermodes of a multicore (MC) fiber ( Fig. 1 ). As compared to recent studies in standard single-core fibers [1] , [2] , the MC p…
