Optical amplifiers are an indispensable part of today's network and face increasingly stringent demands on their performance in terms of peak gain, noise figure, cost, compactness, etc with growing transmission rates, increasing link lengths, wavelength division multiplexing and the continual improvisation of technology. Erbium-Ytterbium codoped fiber amplifier ( EYDFA ) an improvement of Erbium doped fiber amplifier (EDFA), helps overcome the limitation of increase in the concentration of excited erbium ions by countering the pairs quenching phenomenon. This paper investigates the role of optical pumping in dual stage single pass EYDFA and the strong dependence of gain on the pump power till a stage of saturation is reached is observed. Further, an amplifier with high gain of 40-46 dB at 1550nm with low noise figure is simulated for very short lengths of active fiber.

“…However, the effect of attenuation and dispersion in the transmission fiber cannot be eliminated as the signal light propagating through it. This results in some designs on discrete and remote optical amplifier particularly in C-band [1], [2], S-band [3] and L-band [4]- [6] region to overcome this effect. The dispersion effects can be eliminated by introducing dispersion compensating grating, zero dispersion fiber as well as dispersion shifted fiber.…”

We have demonstrated the performance improvement of L-band hybrid remote Erbium-doped fiber amplifier by introducing a phase modulator to suppress the stimulated Brilloiun scattering (SBS) effect in the transmission. The transmission gain has improved by 12.65dB while the noise figure has reduced by 47.1dB when 0dBm signal power is generated at 1590.05nm wavelength. Furthermore, the optical signal-to-noise ratio has improved from 7.81dB to 29.72dB when the signal power is varied from -30dBm to 0dBm. By implementing a phase modulator to the input signal somehow able to produce better performance regarding gain, noise figure and optical signalto-noise ratio, especially at the higher signal power as the gain, has been transferred to the Stokes signal and the amplified signal.

“…Recently, due to the bursty of traffic, the research on gain‐clamping in L‐band EDFAs has received much attention. The gain controllers based on electrical, all‐optical and hybrid schemes have been reported . Comparatively, the linear‐/ring‐cavity‐based optical automatic gain clamping (OAGC) is more popular because of low noise figure and simple configuration.…”

In this letter, we report a novel fiber Bragg grating (FBG)‐based gain controller to simultaneously flatten and clamp the gain spectrum of a long‐wavelength‐band (L‐band) erbium‐doped fiber amplifier (EDFA). Respectively, the single‐ and dual‐FBG schemes are experimentally conducted and investigated in terms of flatness and dynamic stability with various central wavelengths. The results show that, under a suitable central wavelength of FBGs, the high average gain (over 22 dB) and ±0.1 dB stability in ∼30 dBm dynamic range is together guaranteed in our designed amplifier. In gain‐flatness, dual‐FBG scheme presents a smaller fluctuation (∼0.93 dB) in the range of 1570–1610 nm by accurately adjusting the voltage of PZT driver. Comparatively, single‐FBG scheme is more practical and controls the gain‐fluctuation of EDFA below 1.62 dB in the whole L‐band. © 2016 Wiley Periodicals, Inc.
