Biophotonics and nonlinear fiber optics have traditionally been two independent fields.
Since the discovery of fiber‐based supercontinuum generation in 1999, biophotonics …

We report on a new class of polymer photonic crystal fibers for low-loss guidance of THz
radiation. The use of the cyclic olefin copolymer Topas, in combination with advanced …

Photonic quasicrystals are of particular interest for waveguiding applications because of
their beneficial advantages over conventional photonic crystals, such as higher-order …

A special design of a complex-ordered liquid crystal polymer film is developed into a
holographic polarizer. The holographic polarizer shows over 90% transmittance, which …

Nonclassical photon sources of high brightness are key components of quantum
communication technologies. We here demonstrate the generation of narrowband …

Fusion splicing of solid-core microstructured silica fibers has been one of the key enablers
which opened practical applications of these structures in ultrafast light sources or fiber …

Raman scattering has found renewed interest owing to the development of gas-filled hollow-
core fibers, which constitute a unique platform for exploration of novel ultrafast nonlinear …

We study and demonstrate angle-cleaved fusion splicing between single mode fiber (SMF)
and nested anti-resonant node-less fiber (NANF). First, we analyze the trade-off between the …

An exceptionally high-performance, high-birefringent photonic crystal fiber (PCF) is
meticulously designed. The core design features a unique arrangement in which the central …

We demonstrate a novel method for low-loss splicing Ge-doped holey fibers (HF) with
subwavelength core size and high numerical aperture fibers by using a conventional fusion …
