We numerically investigate relative intensity-noise transfer from a noisy pump to the generated Stokes component in random distributed feedback ultralong Raman fiber lasers. Results show transfer levels comparable to those in distributed Raman amplification and cavity-based ultralong Raman fiber lasers, but with some unique spectral features.

    • "In a single unrepeatered span the RIN penalties will be relatively low as the measured RIN of the lasing at 1455 nm at the beginning and at the end of the transmission span was below −120 dB/Hz for all frequencies starting at 332 kHz (Fig. 2). Simulations in reference [11] show that the RIN transfer in random distributed feedback fiber lasers below 332 kHz will have relatively similar values to those observed at frequencies where our experimental RIN measurement started. The transmission fiber used in the experiment was standard Sterlite OH-LITE(E) Single Mode Optical Fiber with approximately 0.19 dB/km loss [12]. "

    ABSTRACT: Transmission of a net 467-Gb/s PDM-16QAM Nyquist-spaced superchannel is reported with an intra-superchannel net spectral efficiency (SE) of 6.6 (b/s)/Hz, over 364-km SMF-28 ULL ultra-low loss optical fiber, enabled by bi-directional second-order Raman amplification and digital nonlinearity compensation. Multi-channel digital back-propagation (MC-DBP) was applied to compensate for nonlinear interference; an improvement of 2 dB in Q(2) factor was achieved when 70-GHz DBP bandwidth was applied, allowing an increase in span length of 37 km.

    • "Since, then, RDF-FLs have been widely studied, due to its simple structure without any " mirrors " and unique output characteristics. These studies related to RDF-FLs include basic emission characteristics [3]– [6], noise and gain optimization [7], [8], high-order and tunable emission [9]–[11], broadband, multi-wavelength, and narrow linewidth outputs [12]–[18]. It is believed that RDF-FL is a good candidate of fiber-optic communication and sensing source, due to its stable output with little thermal sensitivity, wide wavelength tenability, excellent noise and modulation characteristics, spatial incoherence while with a high photonic density of states [19]–[23].

    ABSTRACT: Random distributed feedback fiber laser (RDF-FL) based on combination of Er-doped fiber (EDF) and single-mode fiber (SMF) is proposed in this paper. Through pumping of both the EDF (i.e., 1480 nm pump) and the SMF (i.e., 1455 nm pump), random lasing is obtained. With increase of pump powers, different transitions between chaotic and stable status of the output spectrum are observed. Especially, single-peak random lasing can be obtained under the stable operation regime.

    • "By exploiting the virtual transparency created by second-order Raman pumping in optical fibers [18], a new method to extend the range of Brillouin optical time domain analysis (BOTDA) systems was also proposed and demonstrated [19]. One of the main concerns of the use of this technique is the noise introduced by the Raman pumps, mainly due to relative intensity noise (RIN) transfer from the Raman pumps to the signal [20], [21].

    ABSTRACT: In this study, the authors present an experimental and theoretical description of the use of first order Raman amplification to improve the performance of a Phase-sensitive optical time domain reflectometer $(phi hbox{OTDR})$ when used for vibration measurements over very long distances. A special emphasis is given to the noise which is carefully characterized and minimized along the setup. A semiconductor optical amplifier and an optical switch are used to greatly decrease the intra-band coherent noise of the setup and balanced detection is used to minimize the effects of RIN transferred from the Raman pumps. The sensor was able to detect vibrations of up to 250 Hz (close to the limits set by the time of flight of light pulses) with a resolution of 10 m in a range of 125 km. To achieve the above performance, no post-processing was required in the $phi hbox{OTDR}$ signal. The evolution of the $phi hbox{OTDR}$ signal along the fiber is also shown to have a good agreement with the theoretical model.
