“…These parameters can easily be tailored to increase fiber nonlinearity, which is difficult to achieve using conventional fibers. The highly nonlinear PCFs have many applications such as wavelength conversion [18] and Brillouin fiber lasers (BFLs) [13]. So far, few reports have been published on the Brillouin effects in PCFs [18,19,20].…”

“…So far, few reports have been published on the Brillouin effects in PCFs [18,19,20]. The stimulated Brillouin scattering (SBS) is a nonlinear effect that results from the interaction between intense pump light and acoustic waves in a fiber, thus giving rise to backward propagating frequency shifted light [13]. In BFL applications, the required gain medium length can be substantially reduced using a holey fiber to replace the conventional SMF-28 Fiber of Corning Inc. [21].…”

“…There are also other methods to get simultaneous multi-wavelength outputs such as multiwavelength Raman lasers [10,11], multi-wavelength generation using semiconductor optical amplifiers (SOA) [12] and multi-wavelength Brillouin fiber lasers (BFLs) [13,14]. Special fibers such as dispersion compensating fibers (DCFs) have been used to increase the Raman gain in multi-wavelength Raman fiber lasers where the output power are limited only by the available pump sources [15].…”

“…There are several devices based on Erbium doped optical fibers (EDOFs) such as optical sensors [1], lasers, and optical amplifiers [2,3]. To design and improve such devices, we need to know the main parameters of EDOFs.…”

“…The main technique for measurements of the σ a and σ e without co-dopants can be performed by a theoretical method called as Judd-Ofelt [5][6][7] that is based on atomic level structure. Using Fuchtbauer-Ladenburg equations enables us to evaluate experimentally the steady-state lifetime of the EDOFs, which is an accurate but costly method [2,8,9]. Conventional cutback method (CCM), which is a simple and low cost technique, can be also used to evaluate the σ a and σ e of the EDOFs [2,10,11].…”

Abstract-In this paper, we introduce a different approach of previously reported method to determine absorption and emission cross-sections (σ a and σ e ), and dopant concentration in Erbium doped optical fibers (EDOFs) with low background loss (α). We call this new method as variant input single cutback method (VISCM). There is technical similarity between VISCM and conventional cutback method (CCM) for determination of cross-sections, but in former pump and signal powers are not used together. We numerically verify the effect of different parameters such as input power, background loss, and EDOF amplifier cutback length on the cross-sections using VISCM and CCM. We also present the simulation results of maximum gain and optimum length using obtained cross-sections by two methods. We show that the VISCM presents more accuracy than that of CCM in any conditions. In the presence of α, both CCM and VISCM give not actual but pseudo values for the σ a and σ e . Using pseudo parameters values obtained by VISCM for α < 10 dB/km, the error of maximum gain and optimum length of designed EDOF is shown negligible.

A linear cavity short wavelength band Brillouin/Erbium fiber laser (S-band BEFL) is demonstrated. The architecture utilizes a bi-directional oscillation provided by two optical circulators at both ends of the laser cavity. Therefore, the number of channel is higher in this BEFL compared with the ring-based S-band BEFL. A stable output laser comb with 11 channels was obtained with Brillouin and 980 nm pumps of 9.4 mW and 206.5 mW, respectively at around 1503 nm region. The BEFL has the potential to be used in the future dense wavelength division multiplexing communication system.
