摘要： The present invention provides a compact optical isolator. A polarizer 2A and/or an analyzer 2B of an optical isolator 1 are/is formed of a cobalt magnetic substance minute particle cluster thin film 2. The cobalt magnetic substance minute particle cluster thin film 2 can be formed in the form of tape, film or sheet, whereby the thickness of the polarizer 2A and/or the analyzer 2B can be made small and in addition thereto, the polarizer and/or the analyzer can be formed integrally with a magneto-optical member which is formed in the form of thin film. More compact dimension and lighter weight can be realized as compared with the prior art in which Rochon prism made of calcite, rutile single crystal having wedge form or polarizing beam splitter is employed as the polarizer and the analyzer.

摘要： A Faraday rotator of multilayer film type is provided in which satisfactory optical characteristics are obtained with a small number of layers. In the Faraday rotator, a first periodic dielectric multilayer film made of silicon dioxide SiO2 and tantalum pentaoxide Ta2O5 is formed on a substrate, then a magneto-optical thin film, and a second periodic dielectric multilayer film made of tantalum pentaoxide Ta2O5 and silicon dioxide SiO2 are formed sequentially. The first and second periodic dielectric multilayer films sandwich the magneto-optical thin film such that their respective higher refractive dielectric thin films are in contact with the magneto-optical thin film. The number of layers of the first periodic dielectric multilayer film is larger than that of the second periodic dielectric multilayer film.

摘要： The present invention provides a magneto-optical member capable of ensuring an excellent light transmittance and an optical isolator using the same. A first one-dimensional magnetic photonic crystal having a magneto-optical thin film, and a second one-dimensional magnetic photonic crystal having another magneto-optical thin film are laminated so as to sandwich a dielectric thin film with a small refractive index having an optical length of &lgr;/4+m&lgr;/2 where &lgr; is a wavelength of light and m is 0 or a positive integer. Since a plurality of magneto-optical thin films are present as magnetic thin films and hence the total thickness of the magnetic thin films is increased, the Faraday rotation angle is increased. Also, a large light transmittance can be obtained because of the presence of the dielectric thin film with a small refractive index having (&lgr;/4+m&lgr;/2) thickness where the first and second one-dimensional magnetic photonic crystals are laminated.

摘要： A reflection type Faraday rotator includes first to sixth reflection type sub-rotators. Light is made incident on the first to sixth sub-rotators while repeating reflecting thereat. A Faraday rotation occurs at a sub-rotator having a center wavelength equal to the wavelength of the light The sub-rotators are of reflection-type, have a larger bandwidth of outgoing light compared to a transmission type, and have center wavelengths (wavelength characteristics) different from one another. Thus, the effective wavelength range (the wavelength bandwidth) is increased. Expensive optical devices conventionally required for increasing the wavelength bandwidth are not needed. Accordingly, the cost can be reduced.

摘要： An object of the present invention is to make it possible to record information on an optical information recording medium in the form of three dimensional interference patterns so that the information is erasable in part.The optical information recording medium (1) has an information recording layer (3) made of a magneto-optic recording material. A pick-up (11) of an optical information recording/reproducing apparatus generates information light by spatially modulating laser light emitted from a light source unit (20) with a spatial light modulator (22), and generates recording-specific reference light spatially modulated in phase by spatially modulating the phase of the laser light emitted from the light source (20) with a phase-spatial light modulator (16). The information recording layer (3) of the optical information recording medium (1) is irradiated with the information light and the recording-specific reference light. An electromagnetic coil (30) applies a magnetic field to the information recording layer (3). A three-dimensional distribution pattern of magnetization corresponding to the interference pattern resulting from the information light and the recording-specific reference light is formed in the information recording layer (3).
