An erbium-doped waveguide amplifier (or EDWA) is a type of an optical amplifier enhanced with erbium. It is a close relative of an EDFA, erbium-doped fiber amplifier, and in fact EDWA's basic operating principles are identical to those of the EDFA. Both of them can be used to amplify infrared light at wavelengths in optical communication bands ...

2022年6月16日 · We demonstrate a photonic integrated circuit–based erbium amplifier reaching 145 milliwatts of output power and more than 30 decibels of small-signal gain—on par with commercial fiber amplifiers and surpassing state-of-the-art III-V heterogeneously integrated semiconductor amplifiers.

Erbium-doped double-clad fibers can be used for generating very high output powers of tens of watts or even more. Ytterbium codoping is in that case usually used because the pump absorption efficiency would otherwise be poor.

2024年12月3日 · Erbium-doped thin films deposited through the atomic layer deposition technique hold great potential for achieving excellent optical performance and integration with various material platforms. Here, we demonstrate hybrid erbium-doped waveguide amplifiers using atomic layer deposition and conduct a comprehensive characterization of their gains ...

In this paper, the fabrication and properties of the erbium-doped gallium oxide films are reported. The films are characterized by Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD). The effect of the Er-doping concentration, thermal annealing temperature and film thickness on the photoluminescence properties are studied.

2024年11月10日 · Erbium-doped thin-film lithium niobate (Er:TFLN) provides efficient solutions for monolithic integrated waveguide amplifiers and lasers, as well as the potential for electro-optic modulation and nonlinear application.

5 天之前 · High-concentration Erbium-doped fiber (EDF) is desirable to enable compact erbium-doped fiber amplifiers (EDFAs) by allowing high gain with short lengths of the EDF. However, this has proven to be challenging for silica-based fiber because of relatively poor solubility of Erbium (Er) in silica leading to the formation of Er clusters in high ...

2016年3月24日 · Abstract: This paper discusses erbium-doped fiber amplifiers and its applications. EDFA gain performance and fiber optimization, EDFA saturation and output power, amplified spontaneous emission and noise, amplifier chains, gain spectra, broadband EDFAs and WDM systems, spectral and hole burning in EDFAs, EDFA gain dynamics and power transients ...

2024年8月1日 · Samples of erbium-doped sodium lithium borate glasses were successfully synthesized through an ordinary melt-quenching route and Erbium was added at the expense of borate former up to 5 mol%. The samples were comprehensively characterized using a variety of techniques, including XRD, FTIR, Raman spectroscopy, optical microscopy, UV–Vis ...

2010年12月29日 · 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 high-speed, wavelength-division-multiplexed signals, thus continue to dominate as part of the backbone of longhaul telecommunications networks.
