We report the first long, uniform, optical fibers in which visible light is guided in a single mode by metallic reflection. We describe the fabrication, experiment and characterization of these metallic optical fibers and compare them with theoretical calculations.

    • "In this investigation, the principle of Steiner chains and circle packing are exploited to obtain a non-hexagonal design using a stacking procedure based on hexagonal close packing. Additionally, the cladding air holes of the suggested design can be filled with metal wires using various methods such as fiber drawing [26] and high temperature pressure-cell [27]. Therefore, the suggested design can be fabricated successfully. "

    • "In this paper, we, for the first time, propose the use of a metal wire in the center of the DC-PCF to enhance the directional power transfer. Metal wires in fiber waveguides have attracted a lot of attention in recent years, which are mainly focused on the polarization characteristics and transmission characteristics, for example [5]–[7]. We show that the resonant coupling between the surface plasmon (SP) modes supported by the metal wire and the fiber core-guided modes can also be used to enhance the dual-core fiber coupler performance with a one-order-of-magnitude reduction in coupling length and improvement on CE.

    ABSTRACT: In this paper, we, for the first time, systematically study a new structure of a dual-core photonic crystal fiber filled with a metal wire in the center air hole. Theoretical analysis based on the supermode theory and the coupled-mode theory shows that the directional power transfer between the two fiber cores is enhanced by the resonant coupling between the surface plasmon modes and the fiber core-guided modes. A coupling length reduction of more than one order of magnitude is demonstrated for the new structure in the near-infrared regime. As a new fiber coupler device, the highest coupling efficiency is 81.82%, the insertion loss is as low as 0.87 dB, and the extinction ratio is 30.54 dB at 1550 nm for the optimized design configuration. The new structure is compact in size and easy to fabricate, making it promising for miniaturized complex communication devices.

    ABSTRACT: The “lab-on-fiber” concept envisions novel and highly functionalized technological platforms completely integrated in a single optical fiber that would allow the development of advanced devices, components and sub-systems to be incorporated in modern optical systems for communication and sensing applications. The realization of integrated optical fiber devices requires that several structures and materials at nano- and micro-scale are constructed, embedded and connected all together to provide the necessary physical connections and light-matter interactions. This paper reviews the strategies, the main achievements and related devices in the lab-on-fiber roadmap discussing perspectives and challenges that lie ahead.
