these topics do not cover all the subjects generally associated
with optoelectronics, they do cover major areas presently
identified with this field.
is an introductory level course. It does not aim to examine
all aspects of every topic, nor does it deal with the
topics in great theoretical detail. Instead, we shall
emphasise the basic principles underlying each area, and
aim to highlight the important concepts and devices in
the given area.
relies on a number of disciplines, most importantly optics
and solid-state (semiconductor) physics. It is expected
that students enrolled in this course have some understanding
of these areas. However, where necessary, we shall either
provide a short review of the required material or refer
you to the appropriate reading material.
1 introduces you to the physics underpinning
fibre optics. We shall define the various terms, discuss
the history of fibre optics and review parts of electro-magnetic
theory that is necessary to understand optical wave-guiding.
2 we shall give details of various optical fibres,
fibre materials and the manufacture of optical fibres.
3 deals with attenuation in optical fibres. We
shall discuss the causes of attenuation in optical fibres,
and talk about ways to reduce the overall losses in optical
4 discusses dispersion in optical fibres. In
addition to attenuation, it is dispersion that determines
the key characteristics of communications grade optical
5 reviews the current trends in optical communication
systems, including wavelength division multiplexing and
6 deals with fibre optic sensors. Based on our
understanding of optical fibres from the previous lectures,
in this week we shall discuss a number of active and passive
fibre optic sensors and sensor applications.
7 is the beginning of our journey into semiconductor
physics and optoelectronic devices. We shall review the
fundamentals of the band theory of solids; it is essential
to understand this in order to grasp the workings of optoelectronic
8 deals with the optical properties of semiconductors.
We shall discuss in some detail the properties of various
optoelectronics materials and junctions
9 deals with the details of various types of
semiconductor light emitting devices, including various
laser diodes types
10 gets into the details of various types of
light detectors, and looks at the question of the figures
of merit and sources of noise in detectors
11 describes the electro-optic and acousto-optic
effects that underlie some of the key light modulators
and switches that are in use today, and other non-linear effects.

field of optoelectronics is changing so rapidly that it
is difficult to find one complete textbook. Some of the
topics that were essential a few years ago are today 'ancient
history', while techniques or materials that are important
today are not covered even in books published very recently.
Having said that, a practical and enjoyable textbook that
covers many of the topics that we shall discuss is:
Kasap: Optoelectronics and Photonics, Principles and Practices
(Prentice Hall, Isbn
good reference book (not textbook) is: Optoelectronics,
An Introduction (3rd edition) by J. Wilson
and j.f.b. Hawkes (Prentice Hall, Isbn/Issn: 013103961x)
helpful general introduction to the section on optical
fibres is Understanding Fiber Optics by J. Hecht
(Prentice Hall, 1999 ISBN 0-13-956145-5)
the course we shall solve several example problems in
class. These exercises aim to help you understand specific
topics and provide you with an order of magnitude estimates
for the magnitude of various phenomena.
are two assignments, a mid-session test and a final exam
for this course. The dates and percentages for each assessment
task are given in the table below:
Assignment 1: in class present a 15-20 minutes long
seminar on your research topic. The topic of your research
will be chosen jointly with your lecturer
Assignment2: write a research paper on your research
project. (The paper has to be submitted on or before
the last day of session. No late assignments will be
test: One-hour test on a date specified by the University
Two-hour exam on a date specified by the University
Optoelectronics course is being taught by Professor Mike
Gal. Mike is Professor of Physics and coordinator of the
Optoelectronics and Photonics programs at the School of
Physics of the University of New South Wales. In his 25
years as an academic, he has worked at several universities
in Europe and the USA, and was consultant to numerous
industrial and research organizations. His research interest
is in semiconductor optics and solid-state physics. He
is author of a book, over 150 research publications and
a number of patents.
