Intellectual Property India Publishes Patent Application for 'Polarization Locker For Fiber Connections And Related Methods' Filed by Lightmatter, Inc.

MUMBAI, India, June 13 -- Intellectual Property India has published a patent application (202517036340 A) filed by Lightmatter, Inc., Boston, on April 15, for 'polarization locker for fiber connections and related methods.'

Inventor(s) include Bunandar, Darius.

The application for the patent was published on June 13, under issue no. 24/2025.

According to the abstract released by the Intellectual Property India: "Photonic interconnect systems are described. A fiber connects a first photonic integrated circuit (PIC) to a second PIC. The fiber is non-polarization maintaining and as a results creates polarization drift. As a result, the polarization appearing at the output of a fiber may be different from the polarization launched at the input of the fiber. To reduce the negative effects of polarization drift, each PIC may be equipped with a polarization locker. Control circuitry is configured to control the first and second polarization lockers by setting one of the first and second polarization lockers to an active configuration and setting the other of the first and second polarization lockers to a passive configuration. Controlling the polarization lockers in this way prevents inconsistencies in polarization without having to expend additional resources that would otherwise be required to communicate the phase shift across the fiber."

The patent application was internationally filed on Nov. 09, 2023, under International application No.PCT/US2023/079208.
