LP11a/b mode degeneration in a few-mode fiber is induced by the geometric irregularity of optical fibers. A dual-wavelength resonance of mode coupling from LP01 to LP11a/b modes is found based on the combined effects of optical and acoustic birefringence. Within the configuration of CW intra-cavity laser output, we experimentally demonstrate a fast-switchable generation of LP11a/b modes and optical vortex beams with ±1-order OAM at a switching speed up to 4.3 kHz. This approach has potential applications in mode division multiplexing, particle manipulation, stimulated emission depletion microscopy and quantum information science.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"https://figshare.com/collections/Dynamic_mode-switchable_optical_vortex_beams_using_acousto-optic_mode_converter/4224029/1","contentUrl":null,"metadataVersion":1,"schemaVersion":"http://datacite.org/schema/kernel-4","source":"mds","isActive":true,"state":"findable","reason":null,"viewCount":0,"viewsOverTime":[],"downloadCount":0,"downloadsOverTime":[],"referenceCount":1,"citationCount":0,"citationsOverTime":[],"partCount":0,"partOfCount":0,"versionCount":0,"versionOfCount":0,"created":"2018-11-27T14:08:17.000Z","registered":"2018-11-27T14:08:18.000Z","published":"2018","updated":"2020-07-14T16:55:36.000Z"},"relationships":{"client":{"data":{"id":"figshare.ars","type":"clients"}},"provider":{"data":{"id":"otjm","type":"providers"}},"media":{"data":{"id"
