The performance requirements and device specifications of single mode couplers have been changing rapidly in recent years. This paper reviews the present state of the art in this technology and introduces new device concepts which rely on the fuse-taper technology in their fabrication process. Details will be given of the fabrication and application of single mode wavelength division multiplexers which have an insertion loss below 0.5 dB and have a 20 dB isolation over a 30 nm operating wavelength range. Wavelength division multiplexers with a narrow wavelength separation, <5 nm, will also be described in terms of their fabrication and application. Details of the utilization and performance of concatenated wavelength division multiplexers as filters for uni- and bi-directional communication will also be presented. Finally, techniques for reducing the wavelength sensitivity of the coupling ratio in single mode couplers will be discussed which result in the development of a broad band coupler, BBC.
