Abstract
This device comprises a planar input area (4), a planar output area (6), a microguides array (2) laid out between these areas, means (8) of inputting a light beam associated with the input area and means (10) of outputting a light beam associated with the output area. According to the invention, at least two pieces (12, 16, 22) are formed, one comprising one part of at least one of the areas and the corresponding associated means, the other comprising the other part of this area and the other components of the device, and the pieces are added on so as to form the complete device and to adjust the wave length of this device. Application to optical telecommunications and optical spectrometry.
