Latest Patents

One of Jan Popelek's latest patents is a lithographic method for manufacturing a mask used in the fabrication of a fiber Bragg grating. This invention aims to reduce the effects of stitching errors that can occur during the fabrication process. The first embodiment of this invention utilizes characteristics of stitching errors to compensate for the errors themselves. By increasing the number of stitching errors, the overall impact of these errors can be minimized. A second embodiment introduces continuous writing of the desired pattern, which snaps to a grid that can be processed by the fabrication equipment. This method effectively eliminates stitching errors in the resulting gratings.

Another notable patent involves embodying amplitude information into phase masks. This phase mask is designed for writing fiber Bragg gratings in optical fibers, allowing for adjustments in both amplitude and phase while maintaining a constant mean index of refraction in a single pass. The phase mask integrates amplitude information as an essential part of the phase mask, ensuring that it cannot be separated from the phase information. Various embodiments of this invention include reflective surfaces and polygonal shaped grating regions, showcasing the innovative approaches Jan has taken in his work.
