Wavelength division multiplexer utilizing an optical fibre and colour display as application of the same

摘要

A wavelength-division multiplexing using an optical fiber (10) connected to one of its ends to a set (12) of n sections of fluorescent optical fibers FM1, ..., FMn abutted. Fmi each section, integer i from 1 to n, is doped for retransmitting by fluorescence at a wavelength λMi and is optically coupled to an excitation light source Li capable of producing fluorescence, the various sections FM1 ,. .., FMn being arranged from the end of the fiber (10) in ascending order of their fluorescence wavelength λM1, ..., respective λMn.; Application to the colorimetry and trans port multiplexed information.; The present invention also relates to a color display applying the multiplexing device.
