Abstract
A light source comprising: —at least one semiconductor chip capable of emitting incident radiation: —an output stage comprising at least one fiber or free space for propagating a plurality of predefined modes; —at least one optical part having a microstructured main surface arranged opposite the semiconductor chip for intercepting the incident radiation, spatially modifying the phase of the incident radiation and forming, by a plurality of reflections and/or transmissions on the optical component, transformed light radiation comprising at least the predefined modes.
Claims20
A light source, comprising:
- at least one semiconductor chip configured to emit multi-mode incident radiation;
- an output stage comprising at least one fiber or free space for propagating a plurality of predefined modes;
- and
- a modal transformation device arranged between the semiconductor chip and the output stage, the modal transformation device comprising at least one optical part having a microstructured main surface arranged opposite the semiconductor chip, the modal transformation device configured to intercept the incident radiation during a plurality of instances of reflection and/or a plurality of instances of transmission on the optical part, the microstructured main surface configured to spatially modify the phase of the incident radiation and to form, by the plurality of instances of reflection and/or a plurality of instances of transmission on the optical part, transformed light radiation comprising at least the predefined modes.
