In this paper, the mode coupling mechanism of tilted fiber Bragg gratings (TFBGs) is briefly introduced at first. And a general review on the fabrication, theoretical and experimental research development of TFBGs is presented from a worldwide perspective, followed by an introduction of our current research work on TFBGs at the Institute of Modern Optics, Nankai University (IMONK), including TFBG sensors for single-parameter measurements, temperature cross sensitivity of TFBG sensors, and TFBG-based interrogation technique. Finally, we would make a summary of the related key techniques and a remark on prospects of the research and applications of TFBGs.

“…Advances in grating fabrication methods and fiber photosensitivity enhancement techniques have made it possible to fabricate a variety of index-modulated structures within the core of an optical fiber including Bragg grating (López-Higuera, 2002), long period gratings (Vengsarkar et al, 1996), π-phase shifted grating (Canning and Seats, 1994), blazed or tilted gratings (Erdogan and Sipe, 1995) and various types of chirped gratings (Byron et al, 1993).…”

Problem statement: Monitoring the health of transportation infrastructures is currently reliant on transportation maintenance teams. Scheduled and periodic inspections on most of the infrastructures are performed by manual and visual operations, which are generally time consuming and costly procedures. The use of the fiber optic sensor technology makes it possible to realize continuous, real time and automatic health monitoring for the transportation infrastructure. Approach: This article provided a tutorial introduction to transportation infrastructural health monitoring using fiber optic sensors. Since the topic spans many disciplines, our goal was limited to providing a basic conceptual framework. We began by reviewing the prerequisite topics from structural health monitoring and fiber optic sensors, including a brief review of point and distributed fiber optic sensor technologies. We then provided a comprehensive review of key fiber optic sensors which may be used in the transportation infrastructure monitoring. Results: Point fiber optic sensors were first discussed and then distributed fiber optic sensors. Performances of each sensor are discussed based on the transportation infrastructure monitoring application. Conclusion: We concluded the tutorial with a number of observations on the current directions of the research field of the fiber optic sensor for the transportation infrastructure health monitoring.

In this paper, we discuss theoretical and experimental aspects of nonlinear pulse propagation in long-period fiber gratings. We derive nonlinear coupled mode equations for co-propagating core and cladding modes in a long-period fiber grating and show that the intensity dependent index can be used to tune the mode coupling, thereby creating a mechanism for pulseshaping and all-optical switching. Extensive numerical simulations, which describe the nonlinear pulse dynamics, are compared with experiments. We discuss the application of these nonlinear effects to signal processing in all-optical fiber communications.
