摘要： The present invention aims at providing a connecting method capable of suppressing an influence of stray light for a plurality of optical function devices formed on the same substrate, and an optical apparatus applied with the control method. To this end, in the connecting method of optical function devices according to the present invention, the plurality of optical function devices formed on the same substrate are cascade connected so that both ends of an optical path passing through the plurality of optical function devices are positioned on the same end face of the substrate. According to such a connecting method, it becomes possible to effectively suppress a leakage of stray light from an optical input side to an optical output side.

摘要： The present invention aims at providing a connecting method of optical devices capable of suppressing a periodic wavelength dependence loss and the like, due to the inter-polarization-mode interference caused when connecting a plurality of optical devices by using an optical path having a polarization-preserving characteristic, and an optical apparatus applied with the connecting method. To this end, the connecting method according to the present invention, is to connect a plurality of optical devices to one another by using an optical path of polarization-preserving type having optical characteristics in which a light is propagated along two different polarization axes for substantially equal distances. Thus, even if the polarization direction of the light input/output to/from the respective optical devices is not completely coincident with the direction of the polarization axis of the optical path, it is possible to offset the periodic wavelength dependence loss and the like caused by the inter-polarization-mode interference in the optical path, to be suppressed.
