ABSTRACT:
The device consists of a dual-mode waveguide 1 that has a longitudinal axis 2, 3 and 4, 5, for entry and exit, respectively. In accordance with the are selected in such a way as to establish, in this guide, light coupling that is greater in the window from 1260 to 1360 nm than in the window from 1480 to 1580 nm, so as to compensate for the significant contrary proximity coupling in these windows, as created between the monomode entry guides 2 and 3 on the one hand and the monomode exit guides 4 and 5 on the other hand.
