Light's orbital angular momentum (OAM) is a conserved quantity in cylindrically symmetric
media. However, it is easily destroyed by free-space turbulence or fiber bends, because …

With the rapid advance of integrated optics, the importance of optical waveguides, which are
the fundamental elements of optical integrated circuits, has been widely recognized. For …

The promise of the infinite-dimensionality of orbital angular momentum (OAM) and its
application to free-space and fiber communications has attracted immense attention in …

The field of quantum communication is thriving as a complement to conventional
telecommunication with its distinctive feature of absolute security. As the core technology for …

In this paper, the response of a tapered optical fiber humidity sensor is optimized, attending
to the thickness of the sensitive coating, the dimensions of the taper, the light source, and the …

Electrostatic self-assembly has been used in this work to fabricate a new optical fiber
humidity sensor. Said sensor consists of a single-mode tapered fiber coated with a …

We present for the first time broadband operation of an optical orbital angular momentum
(OAM) erbium-doped fiber amplifier for lower order OAM modes based on an air-hole …

From basic physics to new products, Silica Optical Fiber Technology for Device and
Components examines all aspects of specialty optical fibers. Moreover, the inclusion of the …

The rapid development of fiber lasers is being followed by wide ranges of applications in
laser processing technologies. One of the key parameters to determine the laser–matter …

We report on an ultracompact fiber optic Mach–Zehnder interferometer (MZI) using a novel
concatenated structure, single-mode-fiber (SMF)–hollow optical fiber (HOF)-SMF. An …
