Light source device

An optical device comprising a light source device and an optical component, wherein the optical component comprises a receiving section for receiving light from the light source and an emitting section for emitting light, wherein the light source is a non-coherent light source and is adapted to emit light from a two-dimensional region and wherein the optical component is adapted to guide the light from the receiving section to the emitting section such that the light is emitted in a one dimensional pattern at the emitting section and an optical system arranged in a propagation direction of the light after the emitting section, wherein the optical system is adapted to collimate and/or focus emitted light;

• wherein the optical component comprises a plurality of multimode fibers for guiding light, wherein, within a tapered section positioned between the receiving section and the emitting section, the plurality of multimode fibers are fused together with one another and tapered at the receiving section into a single fiber comprising a single multimode core and separated at the emitting section into the plurality of multimode fibers, and wherein, within the tapered section, the single fiber comprising the single multimode core at the receiving section smoothly transitions to a bundle of fibers comprising the plurality of multimode fibers at the emitting section, the smooth transition achieved by melting a portion of the bundle of fibers together at one point and increasing a length in a specific portion such that a diameter of the tapered section is reduced from the bundle of fibers to the single fiber comprising the multimode core;
• or
• wherein the optical component comprises a plurality of single mode fibers for guiding light, wherein, within a tapered section positioned between the receiving section and the emitting section, the plurality of single mode fibers are fused together with one another and tapered at the receiving section into a single fiber comprising a single multimode core and separated at the emitting section into the plurality of single mode fibers, and wherein, within the tapered section, the single fiber comprising the single multimode core at the receiving section smoothly transitions to a bundle of fibers comprising the plurality of single mode fibers at the emitting section, the smooth transition achieved by melting a portion of the bundle of fibers together at one point and increasing a length in a specific portion such that a diameter of the tapered section is reduced from the bundle of fibers to the single fiber comprising the multimode core.
