Abstract :
A waveguide section intended to host mode-converting optical elements has to be two-moded, at least. However, waveguides of interest such as telecommunication fibers are single-moded in general. In this letter, we demonstrate the UV-writing of two-mode sections in originally single-mode fibers. We discuss the particular properties of mode-converting Bragg gratings written into such two-mode fiber sections.
