摘要： An optical isolator comprising first through fourth plate-like birefringent substances. Each plate-like birefringent substance receives and transmits incident light, and has a corresponding optical axis which is inclined with respect to a direction of the incident light. The optical isolator also has first and second magneto-optical materials, each for rotating a plane of polarization of the incident light. The optical axis of the second plate-like birefringent substance is rotated by one of -45.degree. and 135.degree. about a first axis which is perpendicular to a surface of the first plate-like birefringent substance. The optical axis of the third plate-like birefringent substance is rotated by one of 45.degree. and 225.degree. about a second axis which is perpendicular to the surface of the first plate-like birefringent substance. The optical axis of the fourth plate-like birefringent substance is rotated by one of -90.degree. and 90.degree. about a third axis which is perpendicular to the surface of the first plate-like birefringent substance. The first and third plate-like birefringent substance have equal thicknesses. The second and fourth plate-like birefringent substances are (1+.sqroot.2) times as thick as the first plate-like birefringent substance. The first and second magneto-optical materials rotate the plane of polarization in opposite directions. Finally, the optical isolator has an element for magnetizing the first and second magneto-optical materials.

摘要： An optical isolator not dependent on the plane of polarization of an incident beam and does not allow the plane of polarization to change on the outgoing side. The optical isolator comprises a first parallel flat double refractive crystal substance; a first Faraday rotor for rotating the plane of polarization of a beam; a second parallel flat double refractive crystal substance; a second Faraday rotor for rotating the plane of polarization in a direction opposite to that in which said first Faraday rotor rotates the plane of polarization; a third parallel flat double refractive substance; a fourth parallel flat double refractive substance; and permanent magnets for magnetizing the Faraday rotor and second Faraday rotors. Since a pair of Faraday rotors for rotating the plane of polarization in opposite directions, the plane of polarization on the incident side does not change on the outgoing side.

摘要： A method for manufacturing a fiber-optic collimator which comprises the steps of projecting a beam of light, emerging outwardly from an optical fiber, through a lens onto a planar reflecting medium so as to reflect therefrom, causing the reflected beam of light to enter the fiber through the lens, and adjusting a relationship in position between the lens and the fiber such that the intensity of the reflected beam of light entering the fiber attains a maximum value. The lens and the fiber are then fixed in position when an indication is provided that the intensity of the reflected beam of light has attained the maximum value.
