This research project will demonstrate novel OAM mode convertor technology based on ring core photonic lanterns for nonlinear laser sources in the visible range. Our mode convertors are enabled by innovations in photonic lantern technology that allow high-efficiency generation of custom defined OAM modes of three wavelengths simultaneously. In our system each wavelength is mapped to a particular OAM mode and can be reconfigured. Our photonic lantern mode conversion device can be directly spliced to custom multimode fibers supporting the propagation of OAM mode of high orders.
Benefit: The specific product line that we will have at the completion of the SBIR program will be agile high-power photonic lantern OAM mode multiplexers. This system will advance the Navys laser manned and unmanned platforms. In addition, compared to conventional mode generators based on SLMs, the proposed technology greatly reduces size, is robust and provides broadband mode operation. In addition, our photonic lantern devices can be directly spliced to custom OAM fibers in order to develop high power lasers at non-standard wavelengths on-demand. These unique properties could be utilized to efficiently extend fiber laser sources across the visible band. There are currently no known U.S. suppliers of such photonic lantern systems, and a partnership between Olkin Optics and CREOL through this Phase I can bring such technology to market. The Olkin Optics team believes that the innovations developed here will find a multitude of uses beyond the very specific application need of this SBIR topic, including space-division multiplexed optical communications, super-resolution microscopy, quantum information, etc.
