چکیده

We report the first demonstration of silica-based thulium-doped fiber amplifier (TDFA) working in the 1.65 – 1.7 μm waveband. Up to 29 dB small signal gain and noise figure as low as 6.5 dB are achieved. OCIS codes: (060.2320) Fiber optics amplifiers and oscillators; (060.2330) Fiber optics communications

Comparative Studies of the Thulium and Erbium Doped from 1480-1650 nm with Different Host Materials as Optical Fiber Amplifiers

This work describes the comparison of the amplification characteristics (gain) and the Noise figure (NF) of the Thulium and Erbium in three different host materials which the Yttria Alumina-Silica glass, Fluoride and Tellurite fiber glass. The gain using these host materials covers the range 1.45-1.65 μm. Thulium doped fiber amplifier (TDFAs) operated in the region of wavelength (1480-1510 nm) ...

Exploiting the short wavelength gain of silica-based thulium-doped fiber amplifiers.

Short wavelength operation (1650-1800 nm) of silica-based thulium-doped fiber amplifiers (TDFAs) is investigated. We report the first demonstration of in-band diode-pumped silica-based TDFAs working in the 1700-1800 nm waveband. Up to 29 dB of small-signal gain is achieved in this spectral region, with an operation wavelength accessible by diode pumping as short as 1710 nm. Further gain extensi...

Thulium environment in a silica doped optical fibre

Thulium-doped optical fibre amplifiers (TDFA) are developed to extend the optical telecommunication wavelength division multiplexing (WDM) bandwidth in the so-called S-band (1460–1530 nm). The radiative transition at 1.47 μm (3H4 3F4) competes with a non-radiative multiphonon de-excitation (3H4 -3H5). The quantum efficiency of the transition of interest is then highly affected by the phonon ene...

Thulium-doped silica-based optical fibers for cladding pumped fiber amplifiers

We present preparation and spectroscopic characterization of the Tm-doped fibers with enhanced 3H4 fluorescence lifetime thanks to codoping with alumina. With the alumina content of 10 mol %, the fluorescence lifetime of 58 s was achieved. Using experimentally obtained fiber characteristics, we used numerical simulations to study and optimize for the first time the thulium-doped fiber amplifie...

High average power picosecond pulse and supercontinuum generation from a thulium-doped, all-fiber amplifier.

We demonstrate a high-power, picosecond, thulium-doped, all-fiber master oscillator power amplifier with average power of 120.4 W. The compact fiber oscillator is carefully designed with high repetition rate for the purpose of overcoming the detrimental effects of fiber nonlinearity in the later fiber amplifiers. The pulse duration of 16 ps at 333.75 MHz repetition rate results in a peak power ...
