An optical multiplexing apparatus of a low cost is capable of reliably multiplexing a plurality of optical signals having a narrow wavelength interval, while suppressing the nonlinear optical effect and the crosstalk, and a multiplexing method. The optical multiplexing apparatus includes a first optical...http://www.google.fr/patents/US6904240?utm_source=gb-gplus-shareBrevet US6904240 - Optical multiplexing apparatus and optical multiplexing method
