Bismuth-based erbium-doped fiber as a gain medium for L-band amplification and Brillouin fiber laser
TL;DR: In this paper, the bismuth-based erbium-doped fiber amplifier (Bi-EDFA) is demonstrated to operate at wavelength region from 1570 to 1620 nm using only a 215 cm long of gain medium.
Journal ArticleDOI
Tunable dual wavelength fiber laser incorporating AWG and optical channel selector by controlling the cavity loss
TL;DR: In this paper, a dual wavelength fiber laser (DWFL) based on the use of an erbium doped fiber (EDF) gain medium as well as an 1 × 24 Arrayed Waveguide Grating (AWG) together with two optical channel selectors (OCS) to provide channel spacing tunability.
Journal ArticleDOI
0.16 nm spaced multi-wavelength Brillouin fiber laser in a figure-of-eight configuration
TL;DR: In this article, a stable and compact multi-wavelength Brillouin fiber laser (BFL) operating at room temperature is experimentally demonstrated using a 100 m long photonic crystal fiber (PCF) in conjunction with a figure-of-eight configuration.
Journal ArticleDOI
Multiple wavelength Brillouin fiber laser from injection of intense signal light
TL;DR: In this article, a multiple-wavelength Brillouin fiber laser (BFL) was demonstrated using an injection of intense light at 1480 nm, where the light generated Raman gain at around 1560 nm to amplify the backscattered light in the medium and allowed the generation of multiple lines by selffeedback-seeding effects.
Journal ArticleDOI
An efficient S-band erbium-doped fiber amplifier using double-pass configuration
TL;DR: An efficient short wavelength band erbium-doped fiber amplifier (S-band EDFA) is proposed and demonstrated using double-pass configuration and shows a gain enhancement of about 14dB for pump powers above 120mW.
