Course Instructor

SC306: Fiber Waveguide Optical Engineering

Fiber and waveguide devices are the heart of optical communications technology. This course begins with the essential concepts in the optics of fiber and waveguide devices and proceeds into modeling of cutting edge applications. Simple ray concepts and closed form solutions are explained as well as the basis of eigenmode solutions. Numerical solutions, such as the beam propagation method (BPM) provide the power necessary to model complex, real-world devices. Numerous devices and effects are discussed and illustrated; some with computer generated videos.
