“…As seen from Fig. 2, the experimental histograms are suitably described by the M-fold degenerate Bose-Einstein distributions, where M-values stand for the best fits using formula (2). This reveals that ASE light in our case is a classical thermal source.…”

“…Amplified spontaneous emission (ASE) based light sources are characterized by the broad optical spectrum and high temporal stability, given the absence of relaxation oscillations and interference effects. Such kind of light sources are successful in many applications, including high-precision fiber-optic gyroscopes [1,2], low-coherence interferometry [3], optical coherence tomography [4,5], etc. Recently, it was demonstrated that nanosecond ASE pulses produced by actively Q-switched fiber lasers may provide an effective pump for supercontinuum generation [6][7][8][9].…”

In this paper, we report a study of the features of polarized and unpolarized narrow-band amplified spontaneous emission (ASE) in a low-doped erbium fiber at 976-nm pumping. We demonstrate that ASE noise can be treated as a train of Gaussian-like pulses with random magnitudes, widths, and inter-pulse intervals. ASE noise can also provide a statistical analysis of these three parameters. We also present the data that reveal ASE noise's role in optical spectrum broadening through self-phase modulation of light propagating in a communication fiber. In particular, the data show that the ASE noise derivative defines the broadening's spectral shape.

“…In a relation to FOGs, typical studied issues of the SFS include maximizing a spectrum width [7]- [9] and flatness [6], [7], [10], [11], minimizing a radiation sensitivity [12], [13], but majority of the studies are dedicated to minimizing a temperature sensitivity [3], [14]- [24]. As the measured angular velocity by the FOG is proportional to the Sagnac phase shift with a scale factor depending on the used wavelength, the SFS mean wavelength stability is the most critical parameter.…”

A novel and simple way of improving the mean wavelength temperature stability of the erbium-doped superfluorescent source is described and demonstrated. We show that by introducing small reflectivity feedback at the unpumped fiber end in the backward-pump superfluorescent source configuration, we can affect an overall temperature dependency of the mean wavelength of the output spectrum. The reflectivity adjustment can be made by an angled fiber cleave, varying the reflectivity between 0 to 4 %, or by a fusion arc, allowing its finer adjustment. With this approach, we were able to arbitrarily adjust the mean wavelength temperature trend from -4.38 to 5.23 ppm/ • C. Furthermore, an optimal reflectivity was attained, providing almost zero trend and reducing the total mean wavelength variation to 130 ppm over the temperature range of -40 to +100 • C, which is a 5.7-fold and 4.4-fold improvement compared to 0 • and a standard 8 • fiber cleave angle, respectively. By avoiding any filtering components, a wide bandwidth of 37.8 nm and a power efficiency of 22% was reached. Since the proposed configuration does not include any extra components compared to the basic backward-pump configuration, it can be a viable solution for cost-efficient applications, such as, e.g., mediumgrade fiber-optic gyroscopes. A benefit for these gyroscopes is the tunability of the source wavelength temperature dependency which can conveniently compensate the gyro coil temperature sensitivity.

In the face of the demand for increased communication capacity of fiber optic communication and the requirement for accuracy and stability of various fiber optic devices, the light source, as one of the key devices, is also required to have higher bandwidth and output power. In this paper, this study model and simulate the output spectrum of a quantum-doped optical fiber light source in the range of 1200nm to 1700nm. The rate equation and power propagation equation are established based on the energy level structure of quantum dots. MATLAB solves the numerical model to obtain the output spectra of quantum dot-doped optical fiber light source under different variables. The fiber length, doping concentration, and pumping optical power was further varied to study the effects of several variables on the peak output spectrum. The results show that the fiber length and doping concentration increase and then decrease the peak value of the output spectrum while the pump power increases the peak value of the output spectrum. A pump power of 200 mW was chosen to obtain good experimental results at a fiber length of 3 m and a doping concentration of . The maximum output power is 4.9 mW, and the spectral line width is about 80 nm. The maximum output power is 69 mW, and the spectral line width is about 100 nm at a fiber length of 4 m and a doping concentration of with a pump power of 400 mW.
