The device integrates on the same glass substrate (1) a passive monomode guide (2b) achieved by ion exchange in the substrate and an active monomode guide with lateral confinement by the substrate formed by an active thin layer (4) deposited on the substrate and covering a zone (2a) in the form of a channel achieved by ion exchange in the substrate. The passive monomode guide (2b) constitutes the extension of the zone (2a) in the form of a channel of the active guide. The thin layer (4) comprises a transition zone enabling adiabatic passage of the light from the passive guide to the active guide and vice-versa. The transition zone can be formed by an edge (5) of the layer (4) cutting the axis (S) of the zone in the form of a channel obliquely or by a zone of variable thickness of the thin layer.
