Spatial mode demultiplexing (SPADE) has recently been identified as a promising tool to enhance quantitative performance in super-resolution imaging. While other groups have demonstrated sorting static modes for a specific application, we introduce a first of its kind multi-purpose reconfigurable spatial mode sorter.The sorting is done using a phase-only spatial light modulator (SLM) along with an MPLC (multi-plane light conversion) based algorithm that generates different phase masks for sorting different modes. Our system can easily adapt to sort different, mutually non-orthogonal, spatial mode bases. In this paper we demonstrated the reconfigurability of the system, crosstalk of less than 1% between two orthogonal codewords, and an order of magnitude resolution improvement for two point-sources with separation of up to 0.2 Rayleigh units between them.Type
