OSE6938P - ST: Optical-Fiber Devices: Physics and Applications

The aim of this class is to present a coherent view of the spectacular recent developments in the field of optical-fiber-based devices that make use of a new generation of optical fiber designs. Knowledge of Optical fiber has undergone dramatic change over the last decade, and the range of applications has consequently expanded to cover a plethora of unconventional uses.

Prerequisites

  • Familiarity with electromagnetic concepts and traditional index-guided optical fibers are essential.
