We report a novel “single trench fiber” design for mode area scaling of the fundamental
mode while offering effective single mode operation for a compact fiber laser device. This …

Multi-trench fiber (MTF) is a novel large mode area fiber design for high power fiber laser
applications. This fiber design allows very high suppression of the higher order modes by …

The spectral window around 1700 nm is interesting for in-depth multiphoton microscopy of
intact tissues due to reduced scattering and absorption in this wavelength range. However …

An overview of various designs of large-mode-area photonic bandgap fibers (PBGFs) is
presented in this paper. Bending properties of these structures are discussed and compared …

Very large-mode-area Yb^ 3+-doped single-mode photonic bandgap (PBG) Bragg fiber
oscillators are considered. The transverse hole-burning effect is numerically modeled, which …

A resonant-ring-assisted large mode area segmented cladding fiber (RR-SCF) with a high-
index ring in the core is proposed. Numerical investigations of the effects of the high-index …

A design of a polarizing all-glass Bragg fiber with a microstructure core has been proposed
for the first time. This design provides suppression of high-order modes and of one of the …

Solitonic effects, including multi-solitonic fission and subsequent self-frequency shift, are
used to tailor ultrashort (sub-100 fs) pulses with carrier wavelength broadly tunable in …

This paper presents the results of a detailed theoretical study of the bending properties of all-
glass leakage channel microstructured optical fibers (LC MOFs) with a polymer coating over …

In this work, we perform a detailed study of a novel type of optical fiber for spectral filtering,
which is based on a step-index core with high-index rods embedded into silica cladding …
