Abstract

In this paper we will describe some of the latest developments in the area of optical sources for DWDM systems, including tunable lasers and multiwavelength sources. We will start by introducing the basic technologies used for DWDM sources. After that we will give an overview of the source options, and discuss tuning methods and wavelength control issues. The source options under discussion will include monolithic tunable lasers, hybrid structures and external cavity lasers, tunable VCSELs and wavelength selectable laser arrays. This will include both well established solutions and a number of new laser structures. Numerous specific examples will be shown, and the characteristics and performance of the various devices will be discussed. The key performance parameters, such as tuning range, power and switching speed will be related to the expected areas of application. These areas include sparing, fixed wavelength transmitter replacement, and use in wavelength switched networks.
