The patent application (Publication Number: US20240012196A1) describes a device designed for introducing micro-modifications into optical waveguides. The device includes a focusing optical unit that concentrates laser pulses into the core region of the waveguide, a motor-driven adjustment device for linear movement between the waveguide and the laser beam focus, a holder for the waveguide, and a rotation device for spinning the waveguide. The adjustment device can move the focal position through the waveguide, while the rotation device alters the rotational speed of the waveguide. The movement of the focal position within the waveguide can be adjusted based on the repetition rate, and it can involve a combination of rotational and translational movements.

Furthermore, the device allows for the creation of an ordered arrangement of micro-modifications within the waveguide, with parameters such as symmetry, density, size, and alignment of the modifications being controllable. The device also enables the arrangement of micro-modifications in spiral or helical patterns along the optical axis of the waveguide. Additionally, the patent application includes a variation of the device where the focusing optical unit is rotated around the waveguide instead of the waveguide itself. Overall, the device offers a precise and customizable method for introducing micro-modifications into optical waveguides, with potential applications in various optical technologies.
