Overview

optical fiber for laser

For distributed feedback single-frequency fiber laser

iXblue’s single-frequency fiber lasers are based on UV Bragg grating technology applied to active rare-earth photosensitive fibers. Ultra short cavity length and phase-shifted design permit ultra-narrow linewidth and robust mode-hop-free laser source properties, ideal for various sensor applications.

ECOC 2020

December 2020

We report the design and performance of a single frequency all-fibre 2051 nm distributed feedback (DFB) laser source employing fibre Bragg gratings (FBGs). Output powers up to 36 mW CW and optical signal-to-noise ratios of > 65 dB/0.05 nm are obtained. Heterodyne measurements yield laser linewidths of ~130 kHz FWHM...
