Preface
High-speed optical communication is very much useful in
telecommunication systems, data processing and networking.
It consists of a transmitter that encodes a message into
an optical signal, a channel that carries this optical
signal to its desired destination, and a receiver that
reproduces the message from the received optical signal.
It presents up to date results on communication systems,
along with the explanations of their relevance, from
leading researchers in this field.
The chapters of this book cover general concepts of
high-speed optical communication, optical devices used
optical communication, and optical communication systems.
In recent years, optical devices and other enhanced signal
processing functions are also considered in depth for
high-speed optical communications systems.
Commonly used optical devices are light emitting diodes and
photodetectors.
This book is targeted at research, development and design
engineers from the teams in manufacturing industry, academia
and telecommunication industries.

1. Introduction
Internet traffic is growing very rapidly. Based on Cisco Visual Networking Index (VNI)
forecast and methodology, global IP traffic has increased more than 4 times in the past 5 years,
and will increase 3 times over the next 5 years. Moreover, it will reach 1 zettabyte (ZB) per year
or 83.8 exabytes (EB) per month in year 2015 and exceed 1.4 ZB per year or 120.6 EB per month
threshold by the end of year 2017. Video-on-demand traffic will triple by year 2016. For these
reasons there will be need for optical access networks which are capable to handle with large
data amounts, consume less energy and are cost effective [3].
PONs has been considered to be one of the most promising solutions for access networks due
to its broad bandwidth and low-cost infrastructure [4]. Especially, spectrum sliced wavelength
division multiplexed passive optical network can be an attractive and cost effective solution
to satisfy the growing worldwide demand for transmission capacity in the next generation
fiber optical access networks [1, 2]. In principle there are two major factors that will influence
the telecommunication networks of the future. The first one is the need to support high
bandwidths and low latency and the second one is to use an architecture that is both cost and
energy efficient [5]. Recent studies have uncovered that a large amount of electricity is
consumed by telecom equipment’s in broadband enable countries. Therefore it is important
to put research effort for minimizing energy consumption in fiber optical access networks [6].
Traditional WDM systems have multiple transmitter lasers operating at different wavelengths,
which need to be wavelength selected for each individual channel operated at a specific
wavelength [1, 2]. It increases complexity of network architecture, cost and wavelength
management [7]. The strength of spectrum sliced WDM-PON technology is use of one common
broadband seed light source and its ability to place electronics and optical elements in one
central office (CO), in that way simplifying the architecture of fiber optical network [1]. By
