SC208 - Optical Fiber Design for Telecommunications and Specialty Applications

Monday, 20 March
09:00 - 12:00

Short Course Level: Advanced Beginner


David J. DiGiovanni; OFS Labs, USA

Short Course Description:

Optical fiber development remains a robust field for innovation in both telecom and nontelecom applications.  As worldwide bandwidth demand continues to grow, new fiber types and fiber-based components can increase speed, reduce cost and improve the bandwidth of communications networks.  In addition, application-specific fiber can enable or benefit a wide array of functions such as simply transporting light between two points, amplifying light, processing signals, sensing environmental characteristics and even transporting particles.  The tools available in adapting fiber to particular uses, whether for high speed communications or other applications, include a range of materials and dopants (glasses, polymers), the mechanics of the fiber (size, coatings, microstructure), waveguiding properties (index profile), and creation of various fiber-based devices such as gratings and amplifiers.  These tools have been used to establish an industry that continues to expand as photonics penetrates more and more applications.

This short course will discuss the basics of optical propagation and fiber design, as well as the many ways in which optical fibers can be adapted for a wide range of applications.  We will review an array of current fiber technologies and consider the role and capabilities of materials, structures and waveguide design for both fiber and fiber-based photonic components.   The focus will be two-fold:  coverage of commercial fiber technology, and demonstration of the many opportunities available with novel, specialty optical fibers.   In the former, we will touch on the manufacture, design and properties of optical fiber and utilization issues such as fusion splicing and cabling for conventional, commercial fiber.  Discussion of novel and specialty fiber will include trends for next-generation, high bandwidth communications (designs for advanced modulation formats, space division multiplexing, advanced amplification) as well as the rapidly growing field of non-communications applications in high power fiber lasers, point and distributed optical sensing, and hollow-core optical fiber.


Short Course Benefits:

This course should enable you to:

  • Understand how certain fiber attributes, like attenuation, modal area and dispersion can impact current and next-generation high speed communications technologies.

  • Describe the wide array of optical fibers available and discuss how their designs have been engineered for particular applications.

  • Compare the benefits of different materials in fiber design, including different glass dopants.

  • Understand the difference between fibers used for different applications, such as transmission fiber, amplifiers, and sensors.

  • Determine whether particular applications can benefit from modified or novel optical fiber.

  • Understand the potential offered by fiber engineering which may be exploited to improve existing applications or create new functions.

  • Understand how fiber is used in a wide range of applications, including fusion splicing, fiber management and cabling.


Short Course Audience:

This course is intended for the technical community seeking to understand the basics of optical fiber and waveguide design and the opportunities to adapt fiber for specific applications.  Basic understanding of optical fiber properties is desirable though not required.  The course will provide an understanding of the operating principles of fiber while also exploring the limits of waveguide and materials engineering.  Specific designs for high speed transmission, optical amplification and fiber lasers will be studied, among others.
