We consider a multimode step-index fiber with a high-index coating, where the waves in the slab are evanescently coupled to the modes of the fiber. Conditions for effective resonant interaction are identified. Based on a hybrid analytical–numerical coupled mode model, our simulations predict that substantial fractions of the input power can be focused into waves with specific orbital angular momentum, of excellent purity, with a clear distinction between degenerate modes with opposite vorticity."}],"issue":"5","publication":"Journal of the Optical Society of America B","volume":38,"ddc":["530"],"user_id":"158","_id":"21932","page":"1717","has_accepted_license":"1","status":"public","oa":"1","project":[{"name":"TRR 142 - Project Area C","_id":"56"},{"_id":"53","name":"TRR 142"},{"_id":"75","name":"TRR 142 - Subproject C5"}],"citation":{"short":"M.
