Abrégé

An optical phase-shifting component is used for shifting the phase and modifying the intensity of the light beam injected into the fiber (MMF2). The component is inserted upstream or downstream of, or at an intermediate position in, the fiber. The component uses two mirrors and multiple beam paths between the mirrors. An optical phase-shifting structure (e.g., a reflective phase mask with a structured surface, which can be a mirror) is effective at each reflection of the beam and gradually splits the beam into faster and slower propagation modes. The faster modes are subjected to one or more reflections more than the slower modes and are thereby decelerated. The fast and slow modes are combined again and are then transmitted in a multimode fiber in which the modes have different propagation speeds. The difference in the propagation speeds is thus at least partly compensated.

The invention relates to optical fiber communication, more particularly to modal dispersion compensation in a multimode optical fiber. An optical phase-shifting component (10) is used for shifting the phase and modifying the intensity of the light beam injected into the fiber (MMF2). Said component (10) is inserted upstream or downstream of or at an intermediate position in the fiber. The component uses two mirrors (20, 22) and multiple beam paths between the mirrors. An optical phase-shifting structure (e.g. a reflective phase mask with a structured surface, which can be mirror 22) is effective at each reflection of the beam and gradually splits the beam into faster and slower propagation modes. The faster modes are subjected to one or more reflections more than the slower modes and are thereby decelerated. The fast and slow modes are combined again and are then transmitted in a multimode fiber in which the modes have different propagation speeds. Said difference in the propagation speeds is thus at least partly compensated.

The invention relates to optical fiber communication, more particularly to modal dispersion compensation in a multimode optical fiber. An optical phase-shifting component (10) is used for shifting the phase and modifying the intensity of the light beam injected into the fiber (MMF2). Said component is inserted between an upstream fiber (MMF1) and a downstream fiber (MMF2) which have the same length or approximately the same length if they are identical. The component uses two mirrors (20, 22) and multiple beam paths between the mirrors. An optical phase-shifting structure (e.g. a reflective phase mask with a structured surface, which can be one of the mirrors) is effective at each reflection of the beam. Said structure performs a series of intermediate transformations of the spatial mode of the beam each time the structure is impinged upon by the beam, whereby the slowest propagation modes or groups of propagation modes in the upstream fiber are transformed overall into faster modes or groups of modes, and vice versa, before being injected into the downstream fiber, such that faster and slower propagations occurring in the upstream fiber are compensated in the downstream fiber.
