An automatic switched optical networks(ASON) is an optical transport network capable of automatic switching and routing of optical connections in terms of a control plane. It has rapid provision and expansion of services and fast restoration capability of optical layer. A variety of new devices are required to enable the reliable and effective operation of ASON, including tunable lasers, reconfigurable OXC' s and OADM' s, dynamic gain equalizers, multifunctional integrated optical switches, optical network monitors and so on. This paper overviews the research and development trends of these optoelectronic devices.
