Abstract
A Faraday rotator mirror which is compact, allows high workability of manufacturing and has high reliability and high coupling efficiency is provided. The Faraday rotator mirror comprises a graded-index fiber, a Faraday rotator and a reflector mirror, wherein light incident via the graded-index fiber passes through the Faraday rotator to be reflected on the reflector mirror, and the reflected light passes through the Faraday rotator and emerges through the graded-index fiber.
Claims18
A Faraday rotator mirror comprising:
- a graded-index fiber, a Faraday rotator, a coreless fiber between the graded-index fiber and the Faraday rotator, and a reflector mirror, wherein incident light entering through the graded-index fiber passes through the coreless fiber and the Faraday rotator and is reflected on the reflector mirror, and wherein the reflected light passes through the Faraday rotator and the coreless fiber so as to emerge through the graded-index fiber.
A method of manufacturing a Faraday rotator mirror comprising:
- a process in which a graded-index fiber, a coreless fiber, a Faraday rotator and, a reflector mirror are laid out successively, wherein an optically compatible adhesive is placed in at least one of interfaces between the coreless fiber and the Faraday rotator and between the Faraday rotator and the reflector mirror;
- a process of adjusting a thickness of the optically compatible adhesive in accordance with optical characteristics of an optical system comprising the graded-index fiber, the coreless fiber, the Faraday rotator and the reflector mirror which are disposed as described above;
- and
- a process of hardening the optically compatible adhesive.
