Abstract

We measure the spectral fluorescence emitted by commercial pure-silica core and germanium-doped core fibers in the range of 760-860 nm and find that the broadband fluorescence that exists in the Ge-doped fiber can be avoided by adopting the pure-silica core fiber. Most importantly, we present a narrowband (∼1 nm FWHM) emission line characteristic of zirconia ferrules used in both commercial Ge-doped and pure-silica core fiber patch cables. The results of this work are significant to many applications in the fields of quantum optics and fluorescence spectroscopy, where strong pump light co-propagates with signals at the photon level.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
