Patent 10502898 was granted and assigned to Chiral Photonics on December, 2019 by the United States Patent and Trademark Office.
The inventive circular chiral fiber polarizer is operable to convert linearly polarized light to circularly polarized light, may be advantageously fabricated in an “in-fiber” manner and to comprise desirable extinction ratio characteristics, and may also serve as an interface between a sequentially positioned polarization maintaining (PM) fiber, and a single mode (SM) fiber.
