Abstract
In an embodiment, a sensor element is provided. The sensor element may include a light input configured to receive input light, a sample chamber configured to accommodate a sample, and at least one polymer waveguide optically coupling the light input with the sample chamber, the at least one polymer waveguide including a first contact portion and a second contact portion, wherein at least a portion of the second contact portion may be arranged in the sample chamber. The second contact portion may include a different structure than the first contact portion so that a change of the light intensity of the input light passing through the second contact portion may be caused due to an interaction between the input light passing through the second contact portion and the sample, wherein the change of the light intensity of the input light passing through the second contact portion may be different from the change of the light intensity of the input light passing through the first contact portion.
