Hollow optical waveguide with openings, particularly for supplying a photobioreactor with light and nutrients

A photobioreactor comprising:

• a container for accommodating organisms in a solution;
• at least one optical waveguide having a transparent material and being configured to guide light, the at least one optical waveguide extending into the container and configured to supply the organisms in the container with light, wherein a hollow core is formed by the transparent material to supply the organisms in the container with nutrients, wherein the nutrients transferred in the hollow core exit the at least one optical waveguide outwards and into the solution surrounding the at least one optical waveguide in the container;
• a light source, coupled to the at least one of the optical waveguides in such a manner that light from the light source is coupled into the transparent material of the optical waveguide and can be transferred via the optical waveguide into a solution, to which solution organisms have been added, and
• a nutrient source, which is connected to at least one of the optical waveguides in such a manner that nutrients from the nutrient source are introduced into the hollow core of the optical waveguide and can be transferred via the same into the solution, to which solution organisms have been added.
