Abstract
A light distributor comprising a plurality of optical fibers each having a tapered portion, said tapered portions of the optical fibers being thermally fused together to form a light mixing section where the cores of the fibers are packed together in a single cladding.
Claims7
A light distibutor comprising a plurality of optical fibers with each of said optical fibers having a core located therein that is encapsulated by an individual cladding;
- said light distributor having a tapered light mixing section in which the cladding of adjacent optical fibers remain intact when said optical fibers, held firmly together in a juxtapositional relationship, are thermally fused together to form said tapered light mixing section, said optical fibers being subjected to tensile stresses during said thermal fusion;
- said optical fibers being thermally fused only in the region of said tapered light mixing section;
- whereby a light distributor is formed which distributes optical signals with a small loss of input optical energy.
A light distributor comprising a plurality of optical fibers with individual cladding and with each having a biconically tapered waist;
- said tapered waists of the optical fibers being thermally fused together to form a light mixing section, said optical fibers being subjected to tensile stresses during said thermal fusion, wherein the cores of the fibers are packed in a single cladding and each of the cores is individually retained in the single cladding;
- whereby a light distributor is formed which distributes optical signals with a small loss of input optical energy.
A light distributor comprising optical fibers at least one end of which is conically tapered;
- said tapered end portions of the optical fibers being thermally fused together to form a light mixing section wherein the cores of the fibers are packed in a single cladding and the end face of which is coated with a reflection film;
- said tapered end portions of the cores being separated from each other in the single cladding.
A light distributor comprising:
- a plurality of optical fibers with individual cladding and with each having a biconically tapered waist;
- said tapered waists of the optical fibers being thermally fused together to form a light mixing section;
- wherein the cores of the fibers are packed in a single cladding and each of the cores is individually retained in the single cladding;
- whereby a light distributor is formed which distributes both higher order mode and lower order mode optical signals with a small loss of input optical energy.
