CAPT 3510: Introduction to
Fiber Optics and Photonic Telecommunications Instructor: Regis Fan Course Description
This comprehensive
two-day course is intended to introduce the concepts and issues
associated with fiber based optical systems with an emphasis on the
telecommunication application. The course will focus on the physical
layer and the component technology associated with that layer. First,
the instructor will discuss the physical construction of a fiber as a
waveguide and the associated propagation modes. Then, the
characteristics of the most common fibers including single mode,
multimode and polarization preserving fibers will be discussed. These
characteristics include: numerical aperture, attenuation, chromatic
dispersion, polarization mode dispersion (PMD), polarization dependent
loss and finally, non-linear four wave mixing.
Simple, easy to understand examples will illustrate how these
characteristics impact a communication systems design. The instructor
will show how and why uncorrected dispersion (PMD, chromatic or modal)
limits system bandwidth. Next, the practical aspects of coupling laser
light into a fiber will be reviewed. The attendee will learn how to
optically condition the input light to maximize coupling efficiency.
The sensitivity to angular, lateral and z-axis misalignments will be
presented so that the attendee will understand how to tolerance an
opto-mechanical design. The issues associated with optical feedback
and isolation will be discussed. Methods to recognize and control the
effect of optical feedback will be identified. Fibers form the core
of a telecom system but without a host of passive and active
components, the potential of such systems would be severely limited.
To that end, a good portion of the course is directed to both active
and passive components that are used to construct a practical
fiber-based telecommunications system. Laser sources and their
characteristics and limitations are reviewed including DFB and VCSEL
sources. The techniques to modulate sources (direct, mach-zender etc.)
and the benefits and limitations of those methods are introduced. EDFA,
Raman and SOA optical amplifiers, how they work and how to use them
are also discussed. Passive devices and the principles of operation
will be reviewed. These include circulators, splitters, filters and
gratings. Finally, APD and PIN detectors and the relationship between
signal to noise and Bit error rate will be discussed. The class will
include some basic lab exercises including Cleaving and Inspecting a
fiber, Coupling light into both a single mode and multimode fiber and
observing polarization and loss characteristics with bending. Also,
the lecture portion of the class will demonstrate live measurements of
various characteristics of fiber based components and systems. The course material
will be supplemented with a copy of Fiber Optics Handbook from
Agilent Technology. Who Should Attend
This
course is designed for engineers and technicians of all disciplines
who have just recently been introduced to fiber optic based systems
and have a rising need to understand and utilize fibers and fiber
related technology. Although mathematical content is simplified,
understanding the concepts of trigonometry and calculus are useful.
It is suggested that
a scientific calculator be brought to class to work sample problems. About the Instructor
Dr.
Regis Fan is the CAPT Laboratory Manager. He received his doctorate in
Electrical Engineering from the University of Colorado in 1999 where
his thesis work covered Passive
Polymer Waveguides for Interconnection of Lightwave Components.
His work included analytical modeling of optical interconnects which
includes comprehensive analysis of alignment tolerances, process
development of waveguide fabrication techniques, and performance
evaluation of such devices. He
developed embossed waveguides for out-of-plane coupling using a
directly embossed mirror for VCSEL applications. He has authored and co-authored over a dozen papers on the
various subjects related to optical waveguide component technology.
