Abstract. In the paper the research on rare-earth doped and co-doped optical fibre conducted in the Laboratory of Optical Fiber Technology at the Bialystok University of Technology is presented. Novel active fibre constructions like multicore, helical-core and side detecting ribbon/core optical fibers were developed with a targeted focus into application. First construction i.e. multicore RE doped optical fibers enable supermode generation due to phase - locking of laser radiation achieved in a consequence of exchanging radiation between the cores during the laser action.

Abstract:
We design and fabricate a multicore fiber sensor with the end facets of cores patterned with one-dimensional sub-wavelength Au wire grid polarizers, which are aligned either radially or azimuthally on the cross section of the fiber. With a fan-out device bridging the individual cores and external single core fibers followed by a compact spectrometer, it is able to spatially detect the light intensity, spectrum, and polarization states of the incident light in a highly integrated format. These multicore fiber sensors offer a new opportunity to simultaneously measure multiple optical parameters

Abstract:
We present an autocompensating quantum cryptography technique for Measurement-Device-Independent quantum cryptography devices with different kind of optical fiber modes. We center our study on collinear spatial modes in few-mode optical fibers by using both fiber and micro-optical components. We also indicate how the obtained results can be easily extended to polarization modes in monomode optical fibers and spatial codirectional modes in multicore optical fibers.

Abstract:
We propose the integration of power over ber in the next generation 5G radio access network front-haul solutions based on spatial division multiplexing with multicore bers. The different architectures in both shared- and dedicated- core scenarios for power over ber delivery and data signals are described. The maximum power to be delivered depending on the efciencies of the different components is addressed as well as the limits of the delivered energy to avoid ber fuse and non-linear effects. It is shown how those limits depend on high power laser linewidth, ber attenuation, link length and be

Abstract:
A novel multicore optical waveguide component based on a fiber design optimized towards selective grating inscription for multiplexed sensing applications is presented. Such a fiber design enables the increase in the optical sensor capacity as well as extending the sensing length with a single optical fiber while preserving the spatial sensing resolution. The method uses a multicore fiber with differently doped fiber cores and, therefore, enables a selective grating inscription. The concept can be applied in a draw tower inscription process for an efficient production of sensing networks. Alon

The optical trapping of multiple cells at close proximity allows for cell-to-cell interactions to be studied. Current methods available for creating arrays of traps are free space optical systems that use diffractive optics, laser scanning techniques or the interference of multiple beams to create the multiple traps.

Abstract:
To meet the required future challenge of providing enough bandwidth to achieve high data traffic rates in datacenter links, four-level pulse amplitude modulation (PAM4) signals transmission in short-haul intensity modulation-direct detection datacenters connections supported by homogeneous weakly-coupled multicore fibers has been proposed. However, in such fibers, a physical effect known as inter-core crosstalk (ICXT) limits significantly the performance of short-reach connections by causing large bit error rate (BER) fluctuations that can lead undesirable system outages.
