Fiber Bragg gratings (FBGs) in single-mode fibers, used as narrowband filters, have reached a high maturity level, especially for applications in telecommunications and sensing. In spectroscopic applications, e.g., in Raman spectroscopy, FBG filters

The propagation properties of optical fibers can be significantly influenced by intrinsic stress. These effects are often undesired but in some cases essential for certain applications, e.g. in polarization maintaining (PM) fibers. In this paper, we

We prepared hybrid fibers by filling all-silica capillaries and photonic crystal fibers (PCFs) with arsenic chalcogenide glasses. The filling technology is described in detail and a theoretical model for the prediction of the filling length in combin

Microstructured fibers offer the possibility of being filled with unconventional materials in order to influence the propagation properties in an optical fiber waveguide. We have studied the filling of microstructured silica fibers with electro-optic

Fiber Bragg gratings as key components in telecommunication, fiber lasers, and sensing systems usually rely on the Bragg condition for single mode fibers. In special applications, such as in biophotonics and astrophysics, high light coupling efficien

We present a highly efficient semi-analytical and straightforward-to-implement model for the determination of plasmonic band edges of metallic nanowire arrays inside photonic crystal fibers. The model relies on the approximation of the hexagonal unit

We report a thermo-optic switching effect with a high extinction ratio of 30 dB by means of filling a fluid into air holes of a solid-core photonic crystal fiber (PCF). Such an effect can perform a turn on-off operation of the transmitted light via a

In the present work, the use of a single mode fiber (SMF) with high Germanium doped core as temperature sensor is studied. The fiber core consists of a 1.1 μm highly germanium doped step index waveguide surrounded by a pedestal of 3.5 μm diameter.

In this work, the use of a photonic crystal fiber (PCF) with a highly Germanium (Ge) doped core is exploited as temperature sensor for the first time (to our knowledge). The PCF has an outer diameter of 125 μm and consists of a microstructured cladd

Intrinsic stress in optical fibers significantly influences the mechanical properties of glass and modifies the refractive index. This can have an impact on fiber stability and modal behavior. Corresponding effects are often undesired but in some cas
