“…Recently, another version of B-OCDA that shares some of the characteristics of the ASE-based approach was proposed and demonstrated by Zhang et al from Taiyuan University of Technology [34,35]. In this technique, a semiconductor laser diode is placed within an external feedback cavity, which drives the source into a chaotic regime of operation [34,35]. Noise-like waveforms of GHz-scale linewidths are obtained and used in the generation of the Brillouin pump and signal waves.…”

“…Similar to ASE-based B-OCDA, high-rate external modulation of the laser light is unnecessary, and u(t) is a complex-valued random process. Care was taken to minimize secondary peaks in the auto-correlation function of the chaotic source [34]. As in phase-coded B-OCDA, pulse amplitude modulation of the pump waves was successfully introduced to suppress off-peak Brillouin interactions [35].…”

“…Section 3 of the paper presents the ASE B-OCDA concept and includes previously unpublished analysis of a standard fiber with a spatial resolution of 2 mm. The recent application of the protocol to planar waveguides is addressed [33], and a related concept of B-OCDA based on a chaotic laser source [34,35] is noted as well.…”

Phase-Coded and Noise-Based Brillouin Optical Correlation-Domain Analysis

Correlation-domain analysis has enabled distributed measurements of Brillouin gain spectra along optical fibers with high spatial resolution, up to millimeter-scale. The method relies on the joint modulation of counter-propagating Brillouin pump and signal waves so that their complex envelopes are correlated in select positions only. Brillouin optical correlation-domain analysis was first proposed nearly 20 years ago based on frequency modulation of the two waves. This paper reviews two more recent variants of the concept. In the first, the Brillouin pump and signal waves are co-modulated by high-rate binary phase sequences. The scheme eliminates restricting trade-offs between the spatial resolution and the range of unambiguous measurements, and may also suppress noise due to residual Brillouin interactions outside the correlation peak. Sensor setups based on phase coding addressed 440,000 high-resolution points and showed potential for reaching over 2 million such points. The second approach relies on the amplified spontaneous emission of optical amplifiers, rather than the modulation of an optical carrier, as the source of Brillouin pump and signal waves. Noise-based correlation-domain analysis reaches sub-millimeter spatial resolution. The application of both techniques to tapered micro-fibers and planar waveguides is addressed as well.

“…In Brillouin sensors, it has been demonstrated that the detected BFS value will deviate from the actual one if the temperature or strain change occurs over a length of the fiber shorter than the SR [23]. For Brillouin analysis techniques, cm-scale or even mm-scale SR has been achieved [15,24,25,26], while sub-meter SR for BOTDR is relatively hard to achieve. Therefore, researchers have proposed various methods to improve the SR of BOTDR, as listed below in Section 2.2.…”

In the past two decades Brillouin-based sensors have emerged as a newly-developed optical fiber sensing technology for distributed temperature and strain measurements. Among these, the Brillouin optical time domain reflectometer (BOTDR) has attracted more and more research attention, because of its exclusive advantages, including single-end access, simple system architecture, easy implementation and widespread field applications. It is realized mainly by injecting optical pulses into the fiber and detecting the Brillouin frequency shift (BFS), which is linearly related to the change of ambient temperature and axial strain of the sensing fiber. In this paper, the authors provide a review of new progress on performance improvement and applications of BOTDR in the last decade. Firstly, the recent advances in improving the performance of BOTDRs are summarized, such as spatial resolution, signal-to-noise ratio and measurement accuracy, measurement speed, cross sensitivity and other properties. Moreover, novel-type optical fibers bring new characteristics to optic fiber sensors, hence we introduce the different Brillouin sensing features of special fibers, mainly covering the plastic optical fiber, photonic crystal fiber, few-mode fiber and other special fibers. Additionally, we present a brief overview of BOTDR application scenarios in many industrial fields and intelligent perception, including structural health monitoring of large-range infrastructure, geological disaster prewarning and other applications. To conclude, we discuss several challenges and prospects in the future development of BOTDRs.

“…HAOTIC semiconductor lasers have been used in chaos radar [1]- [5], optical reflectometry [6]- [11], Brillouin optical correlation domain analysis [12], [13], physical random number generation [14]- [17], and chaos-based secure communication [18]- [21], where advantage has been taken of the broadband nature of optical chaos. A semiconductor laser with optical feedback, optoelectronic feedback or single-beam optical injection usually generates chaos with bandwidths around several GHz which limits the range resolution of chaotic lidar, the bit rate of random sequence generation and the transmission rate of optical chaos communications.…”

We show numerically that dual-mode continueswave optical injection into a Fabry-Pérot laser diode subject to optical feedback generates a chaos bandwidth which is four to six times that without optical injection. As a comparison, it is shown that single-mode optical injection can increase the chaos bandwidth threefold with careful choice of detuning. Any combination of dual-mode injection will further enhance the chaos bandwidth and especially for strong injection and over relatively large positive detuning ranges. Even when the bias current of the Fabry-Pérot laser diode is relatively low, the bandwidth of chaos can reach 35 GHz after dual-mode optical injection, which is six times that without optical injection. The enhanced bandwidth with dual-beam optical injection is in accordance with our previous experiments [25]. The present simulations provide detailed guidance on the choice of experimentally accessible parameters to generate chaotic signals with enhanced bandwidth by using single or dual-beam optical injection into a Fabry-Pérot laser diode with optical feedback.
