An all-fiber isolator as an optical isolator comprises: an optical fiber acting as an optical light guide for propagating incident light; and a Faraday rotator for rotating by 45&#xb0; a plane of polarization polarized by the polarizer. The all-fiber isolator exhibits a magneto-optic effect enough to be used as an optical isolator at a visible light wavelength by including quantum dots in a core layer and/or an internal cladding layer of the optical fiber.

Disclosed is a medical mask apparatus using optical fibers which can selectively project a laser beam to an entire treated portion or a local portion of skin. A medical mask apparatus using optical fibers for projecting a fine laser beam to the skin to activate skin cells and expedite circulation of blood in the skin is provided.

Medical mask device which uses optical fibers

The present invention relates to a measurement method of resonant nonlinearity in a nonlinear optical fiber using a long period fiber grating pair. In particular, it relates to a characteristic evaluation method that can simply, but accurately, measure the nonlinear optical characteristics of an optical fiber.
