Fresh off the press! Published today is a simple method for desigining a plasmonic directional coupler in fiber form, for delivering and collecting light on the deeply sub-wavelength scale. This device can be made quite simply by combining fiber drawing with pressure-filling techniques. Another step in the development of hybrid fibers with advanced functionality! I hope other people working on this topic will find this useful, feel free to contact me if you have any questions or would like to use the code for your own designs.
