Multicore fibers (MCF) are a potential key technology in optical communication systems, as its application in spatial division multiplexing (SDM) can beat the transmission capacity limit of single mode fibers. However, the use of MCF can be limited by transmission impairments introduced through the multiple optical paths (e.g., crosstalk and nonlinearities). The use of a spatial light modulator (SLM) to excite the different cores of MCF is expected to mitigate this issue. Additionally, the increasing use and development of photonic integrated circuits (PIC) in telecommunications networks requires improved approaches for the characterization and testing of PIC performance. Thus, a SLM flexible coupling platform based on the diffractive capabilities of the SLM to reconstruct images from computer generated holograms (CGH) is proposed to modulate the wavefront for applications in spatial division multiplexing (SDM) systems and characterization/testing of PIC. A graphical user interface (GUI) was developed to generate/test the phase masks applied to the SLM device. Preliminary results suggest the potential of the SLM based platform employment in SDM systems and PIC testing. Nevertheless, further experimental developments are needed to quantify the feasibility of the platform for multidimensional optical communications systems and PIC assessment.
