Special Symposium on Optical Fiber Sensing Technologies for monitoring in harsh environment
Guillaume Laffont, CEA, France;
Matthieu Lancry, Université Paris Sud, France
Fiber sensing technologies present unique advantages for harsh environment monitoring applications. However particular fibers, coatings, transducers, fabrication and protection mechanisms or even opto-electronic read-out system have to be designed and qualified to improve the sensors performance and lifetime.
This special symposium forms part of the 2018 BGPP Topical Meeting, and we are seeking submissions reporting on the latest research and development related to the use of fiber optic sensing technologies to perform monitoring under harsh environments. These elements can be low or high temperatures (typically well outside of standards defined for telecommunications), high strain, high pressures, high voltage, high magnetic fields, vibrations, dust, explosive environments, and aggressive chemical and biological environments.
The scope of this symposium covers all topics associated with fiber sensing in harsh environments including transducers, sensors, fabrication methods, packaging, interrogators and miniaturization, qualifications, standardization and field deployments. The topics of solicited papers cover, but are not limited to, the following domains:
- Sensing-specialized optical fibers, coatings and materials;
- Distributed, quasi-distributed and point fiber sensors;
- Rayleigh, Raman and Brillouin distributed fiber sensing;
- FBGs for low temperature (cryogenic) applications (nonlinearity);
- FBGs for high temperature applications ( (increased thermal reliability);
- FBGs for high strain applications (increased mechanical reliability);
- FBGs for ionizing radiation environment (increased radiation reliability);
- FBGs for applications in undersea and free space communication, oil and gas industry, aerospace missions, deep space, interplanetary etc.
- Effects of harsh environments (temperature, strain, pressure, ionizing radiation, etc.);
- Effects of high electric and high magnetic fields
- Integration, packaging, deployment, and field tests of FBG sensors;
- Miniaturized fiber sensing systems suitable for aircraft, satellites and other spacecraft (space and weight limitations);
- Cycling and reproducibility;
- Reliable optical fiber sensing systems for communication, oil and gas industry, aerospace missions, etc.
- Performance of FBG systems in standard and harsh environments;
- Standardization for different industries and applications.
- Universal standards across harsh environments
Special Symposium on Innovative Grating-components and Grating-configurations for Fiber Lasers
Martin Bernier, COPL, Canada
; Morten Ibsen, ORC – University of Southampton, UK
The past two decades have seen fiber lasers develop from a laboratory curiosity into a truly competitive technology now surpassing more traditional laser systems and opening up new and exciting application areas of laser technology. The advances in fiber laser performance have to a large extent been facilitated by the use of fiber gratings to control and tailor the output characteristics.
This special symposium forms part of the 2018 BGPP Topical Meeting, and we are seeking submissions reporting on novel and innovative configurations of gratings, including fiber and volume Bragg gratings, in conjunction with fiber lasers to further their performance and facilitate new application areas. In particular, papers are being solicited to cover innovative gratings and grating configurations from their design and optimization, through to their fabrication and application.
The topics of solicited submissions include but are not limited to grating components and configurations for:
- High power cw and pulsed fiber lasers (FLs)
- Dispersion and pulse-shape control in pulsed FLs
- Narrow linewidth and wavelength tunable FLs
- Linear- and ring-cavity FLs
- Random FLs
- FLs in compound glasses incl. soft glasses
- Up- and down-conversion FLs for extended wavelength coverage
- High power diode wavelength stabilization
