W-type and Graded-index bismuth-doped fibers for efficient lasers and amplifiers operating in E-band

A. S. Vakhrushev et al.

Summary: This paper focuses on the fabrication and investigation of optical properties of W-type and Graded-index single-mode Bi-doped germanosilicate fibers. By varying the doping profile, the characteristic parameters of the active medium can be changed, leading to an improvement in the performance of optical devices based on these fibers. The experimental results demonstrate the successful creation of a Bi-doped fiber laser operating at 1460 nm with a record efficiency of 72% and a 20-dB Bi-doped fiber amplifier with a high gain efficiency of 0.52 dB/mW.

Ultra-Broadband Bismuth-Doped Fiber Amplifier Covering a 115-nm Bandwidth in the O and E Bands

Yu Wang et al.

Summary: This article presents an experimentally demonstrated all-fiber optical amplifier using Bi-doped phosphosilicate fiber, achieving >20 dB gain in both the O-band and the E-band. The amplifier provides a maximum gain of 31 dB and an in-band OSNR of >22 dB at 1420 nm, with a gain coefficient of 0.04 dB/mW for a -23 dBm input signal. Temperature dependent gain and NF performance were characterized within -40 to +60 degrees C.

Pump-efficient flattop O plus E-bands bismuth-doped fiber amplifier with 116 nm-3 dB gain bandwidth

Yan Ososkov et al.

Summary: A new record in the field of broadband BDFA in the O+E spectral range was reported, achieving high gain with low pump power using a bismuth-doped fiber. Different pump wavelengths were compared, with the shortest wavelength providing wider gain bandwidth but requiring higher pump power, while the longest wavelength offered higher pump efficiency but narrower gain bandwidth. Multiple wavelength amplification effects were also studied to reveal potential issues with broadband signal amplification in such amplifiers.
