Novel multicore structures

Calculated intensity distribution of 127 nuclei randomized in size and arrangement in hexagonal overall arrangement.

Multicore fibres with thousands of cores are a well-established technology in endoscopy. They transfer 2D intensity images from the distal to the proximal fiber end. However, a 3D imaging or light-field control becomes only possible, if not only the intensity but also the phase is recorded or controlled. This so-called lens-less endoscopy is of outstanding interest for various applications, e.g. in biomedicine. Traditional multicore fibres have periodic core layouts and are quite sensitive to bending variations. The periodic layout leads to unwanted coherent side-lobes if the 3D light field at the distal end is controlled remotely from the proximal end. Thus, we are working on novel aperiodic multicore designs, which will even be insensitive to bending variations. A particular goal of us will be to develop a scalable productions process that can be scaled to very large multicore designs. In addition, we are investigating strategies to suppress the core-to-core power coupling - a goal which will also be of relevance for future telecommunication concepts based on multicore fibres.
