The standardization of photonic integration processes for InP has led to versatile and easily
accessible generic integration platforms. The generic integration platforms enable the …

Intermixing the wells and barriers of quantum well structures generally results in an increase
in the band gap and is accompanied by changes in the refractive index. A range of …

We demonstrate the highest-quality Bragg gratings reported to date in chalcogenide glass
rib waveguides, both in strength and apodization. A modified Sagnac interferometer is …

Lithium niobate's use in integrated optics is somewhat hampered by the lack of a capability
to create low loss waveguides with strong lateral index confinement. Thin film single crystal …

A review is presented of recent progress in low-loss III-V semiconductor integrated optics for
the 1-1.6 mu m wavelength range, including propagation, bending, coupling, and modulator …

Multimode interference devices are very versatile components that are often used as
components for power splitting or combining in larger circuits. In this paper, we present a …

A high precision measurement technique for characterizing the propagation loss in silica low-
loss optical waveguides, based on measuring the contrast of a Fabry-Perot cavity, is …

Single-line photonic-crystal waveguides are investigated. Photoluminescence experiments
and three-dimensional calculation are performed and allow a clear identification of the …

We demonstrate the fabrication of single-mode optical waveguides on lithium niobate on an
insulator (LNOI) by optical patterning combined with chemomechanical polishing. The …

An investigation was made of the optical and waveguiding properties of thin films fabricated
from solutions of chitosan‐acetic acid (chitosan/HAc) and chitosan/HAc doped with rare …
