Photonic lanterns are made by adiabatically merging several single-mode cores into one
multimode core. They provide low-loss interfaces between single-mode and multimode …

A taper transition can couple light between a multimode fiber and several single-mode
fibers. If the number of single-mode fibers matches the number of spatial modes in the …

We investigate the self-trapping phenomenon in one-dimensional nonlinear waveguide
arrays. We discuss various approximate analytical descriptions of the discrete self-trapped …

We demonstrate that nonlinear optical fiber arrays can support stable solitonlike pulses with
finite energy. The bound state that we have found is localized both in time and in spatial …

The idea to write a new book in the? eld of ferroelectric crystals arose from some
considerationsreportedinthefollowing. Inthelast5years, severalgroupsallaround the world in …

A novel concept of 1× 16 power splitter based on a variable multicore photonic crystal fiber
(PCF) structure is described. Numerical simulations showed how the optical signal can be …

Featured Application The proposed device can be very useful to high power and parametric
applications. Abstract A novel concept of 4× 1 power beam combiner based on multicore …

We report a new method to fabricate a 4× 1 signal combiner that comprises an output fiber
port and a tapered fused bundle (TFB) with four input fiber ports. The TFB is etched in a …

A hexagonal array not only is a nature-preferred pattern but also is widely used in
optoelectronical materials and devices. We report a simple method of hexagonal array …

This study uses the beam propagation method to propose a new design of multicore
photonic crystal fiber-based 1× 8 two-dimensional splitters. An optical signal at a wavelength …
