We demonstrate the generation of ultrabroad spectra in a photonic crystal fiber with a kagome-lattice transverse structure. This two-dimensional periodic photonic lattice allows for strong confinement of light without employing defect states nor usin

In this paper, we report that diffractionless propagation is also possible in the visible spectral range by downscaling the slab system as well as the PC parameters. The experimentally obtained wavelengths for optimal guidance are in excellent agreem

We demonstrate a MFL with a single 5-air-hole annulus yielding a 280-mW output power at 52% slope efficiency. This high efficiency is attributed to a novel doping process and a special design of the MFL

We report on the light propagation in a one-line-defect photonic crystal waveguide (W1 PhC WG) patterned into a 450 nm thick free-standing lithium niobate membrane by ion-beam enhanced etching. The Bloch wave vectors and transmission spectrum of this

Symmetrical optical power T-splitters were fabricated using miniaturized 90° bends with a curvature radius of 2μm and a high transmittance of almost 99% per bend. A constant excess loss of only 1.4dB was achieved at a photonic wire width of 450nm o

We report on the design of a single-polarization single-transverse mode large mode area photonic crystal fiber. By including index-matched stress applying elements in the photonic cladding an ultra-broadband single polarization window is obtained whi
