Abstract
A wave guide may have an index profile including at least one maximum. The maximum or maxima of the index profile may correspond respectively to at least one maximum intensity of the outlet radiation with a mode of desired order. The wave guide may also have at least one doping ion configured to absorb the pump radiation. The doping ion or ions may have a concentration profile of doping ions including at least one maximum.
Claims11
A non-linear multimode wave guide configured to generate a substantially single-mode outlet radiation with a mode of desired order from a substantially single-mode inlet radiation in the spatial domain and in the time domain, the inlet radiation being coupled with a pump radiation, wherein the wave guide has:
- an index profile according to a transversal cross-section of the wave guide comprising at least one maximum, the maximum or maxima of the index profile corresponding respectively to at least one maximum intensity of the outlet radiation with the mode of desired order;
- at least one doping ion configured to absorb the pump radiation, the doping ion or ions having a concentration profile of doping ions according to the transversal cross-section of the wave guide comprising at least one maximum.
