OPTICAL DEVICE WITH PROXIMITY COUPLING BETWEEN TWO INTEGRATED WAVEGUIDES WITH REDUCED DIMENSIONS AND INTEGRATED OPTICAL COMPONENT BY APPLYING THEM.

摘要

P The device, used for the separation or joining of two radiations of different wavelengths, is of the type in which the waveguides comprise straight portions of interaction (11, 21; 11 n, 21 n) parallel and close to each other and curvilinear inflection approach portions (12, 22, 13, 23; 12 n, 22 n, 13 n, 23 n) connected to ends of the straight portions and for some, to inputs / outputs (4, 5, 6) of the device. According to the invention, the approach parts located on at least one side of the straight portions are devoid of any inflection, the coupling of the straight portions being possibly modified to compensate for the variation of the coupling between the waveguides along said parts of approach, due to the suppression of inflections. / P
