TL;DR: In this paper, the authors propose a composant appeleme "TRIMAX" with a concurrency of 0,825, 0,87 and 1,3 μ.
Abstract: Un multiplexeur a filtres fonctionnant sur trois canaux est decrit. Il est base sur le couplage de la fibre de ligne avec chacune des fibres d'emission ou de reception par des miroirs concaves travaillant au centre de courbure et presente peu d'aberration. L'extraction de chaque longueur d'onde ou son injection dans la ligne se fait par reflexion selective sur les miroirs a couches multidielectriques. Le composant appele « TRIMAX » a ete concu pour fonctionner a 0,825, 0,87 et 1,3 μ. Les pertes sont inferieures ou egales a 0,3 dB pour la premiere voie, 0,75 dB pour la deuxieme voie et 1 dB pour la troisieme. Un taux de para-diaphonie aussi bas que — 78 dB a ete mesure entre voies proches. La distance intracanaux a — 50 dB de paradiaphonie et 1 dB de perte peut etre reduite jusqu'a 25 nm. Un composant appele « BIMAX », destine a separer 0,8 de 1,3 μ a egalement ete fabrique. Les pertes sont bien inferieures a 1 dB pour les deux voies et le taux de rejection de 0,8 sur 1,3 μ tres eleve.

TL;DR: In this paper, an optical fiber demultiplexer comprises first (325b) and second (325c) ports located in the focal plane of a first spherical reflective surface (313) such that light at one port is focused on the other.
Abstract: An optical fiber demultiplexer comprises first (325b) and second (325c) ports located in the focal plane of a first spherical reflective surface (313) such that light at one port is focused on the other. A second spherical reflective surface (315) which is dichroic is located between the ports and the first spherical surface and has a focal plane common with that of the first spherical surface. A third port (325a) is located in the common focal plane such that light from the first port of the frequency reflected by the dichroic surface is focused at the third port (325a).

TL;DR: In this paper, optical wavelength division multiplexers (WDM) were tested for performance degradation as a result of temperature cycling, shock and pulling on the fiber leads to determine tensile strength.
Abstract: Optical wavelength division multiplexers (WDM) were tested for performance degradation as a result of temperature cycling, shock and pulling on the fiber leads to determine tensile strength. The WDM components tested use multidielectric coatings to separate two channels, one ranging from 0.75 to 0.95 micron and the other from 1.2 to 1.6 microns. The optical crosstalk remained constant under the various tests and the insertion loss variation was small.
