Article Synopsis
- Researchers designed a new type of erbium-doped few-mode fiber for use as an optical amplifier, focusing on mode-division multiplexing.
- The fiber features 19 doped regions embedded in a structure that allows it to support 10 signal modes, aiming to balance the gain across these modes.
- Experimental evaluations were conducted to assess the amplification properties, along with the use of custom dual-wavelength mode multiplexers to optimize signal and pump beam shaping.
We propose and fabricate a novel ring-core photonic crystal fiber made of a circular ring core surrounded by a cladding constituted of air holes organized in a first circular ring surrounded by hexagonal ones. The fiber efficiently supports four different groups of orbital angular momentum (OAM) modes. The effective indices of spin-orbit aligned and spin-orbit anti-aligned modes in the same OAM modes group are separated by at least 2.
