Erbium‐doped fiber devices have been extraordinarily successful due to their broad optical
gain around 1.5–1.6 µm. Er‐doped fiber amplifiers enable efficient, stable amplification of …

One of the major driving forces for the development of new glasses is the demand for high
optical non-linearity with reduced cost and a higher damage resistance. Oxide glasses with …

A reliable and reproducible deposition process for the fabrication of Al 2 O 3 waveguides
with losses as low as 0.1 dB/cm has been developed. The thin films are grown at~ 5 nm/min …

In this work, we report low-loss single-mode integrated optical waveguides in the near ultra-
violet and visible spectral regions with aluminum oxide (Al2O3) films using an atomic layer …

Titanium doped sapphire (Ti: sapphire) is a laser gain material with broad gain bandwidth
benefiting from the material stability of sapphire. These favorable characteristics of Ti …

Exhaust mufflers, large exhaust stacks, and turbofan engines are common examples of
ducted noise. The most useful measure of the sound produced by these noise sources is the …

For the past decade, erbium-doped integrated waveguide amplifiers and lasers have shown
excellent potential for on-chip amplification and generation of light at the important …

Wide aperture omnidirectional free-space optical (FSO) receivers using wavelength shifting
(WLS) fibers that enable the use of small active area high-speed photodetectors in optical …

In the given review, optical transoceanic or transcontinental telecommunication system, as
the core of the modern information technology, has been taken into consideration as a …

We report high light extraction from the top emission OLED (TEOLED) device structure by
improving mainly the waveguide mode loss in the atomic layer deposition processed thin …
