Mode division multiplexing has been mooted as a future technology to address the impending data crunch of existing fibre networks. Present demonstrations delineate the light source from the mode creation steps, potentially inhibiting integrated solutions. Here we demonstrate an integrated mode generating source in the form of a digitally controlled solid state laser with an intra-cavity spatial light modulator. In our proof-of- principle experiment we create fibre modes on demand and couple them directly into a few-mode fibre, where after transmission they are decoupled by modal decomposition. This is the first demonstration of a single source for encoding information into the spatial modes of light.
