Latest Patents

Kjellberg's latest patents include a method for forming a longitudinal solid body within an optical fiber. This method involves placing a first end of the optical fiber in a heating chamber while keeping the second end outside. Molten material is then forced into the longitudinal hole of the fiber, and the fiber is extracted at a controlled rate. This process allows for the creation of solid bodies within the fiber, enhancing its functionality.

Another notable patent is a method and device for controlling the refractive index in an optical fiber. This invention utilizes a longitudinal electrode running along the core of the fiber. By passing an electric current through the electrode, thermal expansion occurs, creating a compressing force on the core. This compression alters the refractive index and induces changes in birefringence, which is crucial for various optical applications.
