Abstract

In this letter, a wavelength-tunable fiber amplifier operating in C + L band was demonstrated. The gain equalization between C-band and L-band was verified through the simulation. Subsequently, we build a C + L band wavelength-tunable erbium-ytterbium co-doped fiber amplifier. The tunable wavelengths were ranging from 1540 nm to 1615 nm with the total bandwidth of 75 nm. Besides, based on the gain fiber length of 6.5 m and the maximum pump power of 400 W, over 100 W output power was achieved at each wavelength accompanied with a good beam quality. Our results provide guidance for the application of C + L band high power fiber laser and amplifier.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
