MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202647074850 A) filed by Xilinx, Inc. on June 17, 2026, for Process Variation-Tolerant Cascaded Tapered Optical Ring Resonators.
Inventors include Parsons, Robert; Xie, Chuan; and Raj, Mayank.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: Embodiments herein describe a method for selectively filtering different wavelengths of optical signals received from an optical channel using cascaded ring resonators, each of the cascaded ring resonators having a first ring and a second ring. The first ring has a varying waveguide width along its length configured to form a first waveguide width portion and a second waveguide width portion, the first waveguide width portion having a greater width than the second waveguide width portion. The second ring has a varying waveguide width along its length configured to form a third waveguide width portion and a fourth waveguide width portion, the fourth waveguide width portion having a greater width than the third waveguide width portion. The method further connects receivers to respective cascaded ring resonators, each of the receivers having a photodetector configured to differentiate between the optical signals.
