“…1 Since the 1.54 m emission from Er ions corresponds to the low-loss window in the absorption spectrum of silica optical fibers for optical communications, 2,3 Er has received attractive attention and been widely studied. Due to the predominance in the microelectronics industry, Si has been chosen for the primary host material.…”

Erbium-doped GaN with different doping concentrations were grown by ammonia-source molecular beam epitaxy. The intra-4f-shell transitions related green luminescence were observed by both photoluminescence ͑PL͒ and cathodoluminescence ͑CL͒ measurements. It was found that concentration quenching of Er-related luminescence was observed in PL measurements while not in CL measurements. The different excitation and relaxation processes are suggested as the cause of the concentration quenching characteristics between PL and CL. The strong Er-related CL intensity in highly doped GaN demonstrates that high energy excitation is a promising approach to suppress the concentration quenching in Er-doped GaN.

Abstract.A passively Q-switched erbium-doped fibre laser is experimentally implemented, using molybdenum disulfide (MoS 2 ) and tungsten disulfide (WS 2 ) as saturable absorbers. The results testify that a WS 2 -based Q-switched fibre laser generates more stable pulse trains, if compared with the MoS 2 -based saturable absorber. The wavelength region where the Q-switched pulses have been obtained is a so-called C-band region. The central wavelengths are 1559 and 1560 nm for MoS 2 and WS 2 , respectively.

“…[1][2][3] From that time until the late 1980s, such fibers were primarily a research platform, which did not mature into commercial products. This changed very dramatically with the development of the erbium (Er)-doped fiber amplifier (EDFA), 4 which provided the first realistic solution to the rising critical need for an all-optical amplifier within optical communication systems. The success of the EDFA and the subsequent advancement of high power fiber lasers and amplifiers for telecommunications, industrial materials processing (welding, drilling, cutting, micromachining), medical (imaging, surgery, therapeutics), military (weapons, imaging, ranging), and environmental monitoring (fiber optic sensing) applications, spawned an industry that even today maintains continuous growth.…”

Articles you may be interested inFiber-optic thermometer application of thermal radiation from rare-earth end-doped SiO2 fiber Rev. Sci. Instrum. 85, 084903 (2014) Rare-earth doped optical fibers have captivated the interest of many researchers around the world across the past three decades. The growth of this research field has been stimulated primarily through their application in optical communications as fiber lasers and amplifiers, although rare-earth doped optical fiber based devices are now finding important uses in many other scientific and industrial areas (for example, medicine, sensing, the military, and material processing). Such wide commercial interest has provided a strong incentive for innovative fiber designs, alternative glass compositions, and novel fabrication processes. A prerequisite for the ongoing progress of this research field is developing the capacity to provide high resolution information about the rare-earth dopant distribution profiles within the optical fibers. This paper constitutes a comprehensive review of the imaging techniques that have been utilized in the analysis of the distribution of the rare-earth ion erbium within the core of optical fibers.
