We demonstrate a simple-to-fabricate refractometer based on the inscription of fiber Bragg gratings in a special C-shaped optical fiber. The C-shaped fiber was drawn into shape using a quarter cladding removed preform of a commercial standard single-

An illuminating fiber is demonstrated by incorporating a reflecting element along a fiber. The element creates a helical path longitudinally to efficiently scatter light. We present the concept and its demonstration in a 200-|rm fiber.

Abstract The osteochondral interface is a thin layer that connects hyaline cartilage to subchondral bone. Subcellular elemental distribution can be visualised using synchrotron X-ray fluorescence microscopy (SR-XFM) (1 μm). This study aims to determ

We report a fabrication route to achieve highly GeO2-doped silica fibers with GeO2 molar concentration as high as 74% using the conventional modified chemical vapor deposition (MCVD) process. The dependence of background loss on fiber frozen-in stres

A microstructured optical fiber (MOF) structure with longitudinal dispersion variation is theoretically investigated for broad, coherent supercontinuum (SC) generation in the infrared (IR) region. The MOF possesses anomalous dispersion at 1550 nm but

We present a silica-based thulium-doped fibre amplifier in the 1628–1655nm waveband based on Tm/Ge co-doped fibre. Up to 19dB external small signal gain and a noise figure of 4.4dB are achieved at 1655nm.

We fabricate and characterize a germanium/thulium (Ge/Tm) co-doped silica fiber in order to enhance the gain at the short wavelength edge of the thulium emission band (i.e. 1620-1660 nm). The Ge/Tm doped fiber shows an intrinsic blue-shifted absorpti

We investigate mode-area scaling by means of supermode operation in an all-solid multicore fiber. To obtain a large-mode area (LMA), we designed and fabricated an active double-clad multicore fiber, where each ytterbium-doped core is 19 μm in diamet

A non-circular core Yb-doped fiber was fabricated in-house. Nearly 200 W output power was obtained with this fiber in a linear cavity. The slope efficiency was 67%. The measured $M_{x,y}^2$ was 1.5 and 3.1, respectively.
