Abstract

PURPOSE:To divide and synthesize multichannel low-loss lights, by repetitively reflecting and propagating light waves through a plurality of light BPF trains having different band-pass widths, which are provided on the two parallel surfaces of a substrate. CONSTITUTION:Multichannel light waves with wavelengths of lambda1, lambda2, ..., which are incident to a device by way of a rod-shaped lens 40 and a prism 80, are repetitively reflected and propagated through a plurality of light BPFs 11 to 16 with different band-pass widths which are provided on both surfaces of a substrate 60. The light waves, which pass through the light BPFs 11 to 16 depending on the wavelengths in such a way, is separated by a fiber 100, which is optically connected to light fibers 51 to 56 through prisms 81 to 86 and rod-shaped lenses 41 to 46 and which does not leak the propagating light, by the lenses 40 to 46, by the fibers 51 to 56, and the like. Furthermore the alignment of the lenses 40 to 46, the adjustment of the incident angles by the prism angles, and the like are readily performed, thereby the multichannel lights can be separated with low losses. Furthermore, synthesization of multichannel lights can be made by the same method.
