摘要： In an optical transmission line consisting of a multimode optical fiber, the mode dispersion of the optical transmission line is reduced in order to permit a wide-band optical signal to be transmitted at high speed, over a long distance and at low costs. When a plurality of multimode optical fibers are connected together to form a transmission line for the purpose of reducing a mode dispersion, length ratios between the respective multimode optical fibers that can maximize the band of this optical transmission are determined, and they are connected together at the length ratios. In addition, a multimode optical fiber having a specific refractive index profile is used as a mode dispersion compensating fiber. Also, a compensated fiber and a compensating fiber each having a specific length are connected together.

摘要： When a wavelength of a first laser beam with which a first recording medium including a first recording layer is recorded and reproduced is indicated as λ1 (nm), a wavelength of a second laser beam with which a second recording medium including a second recording layer is recorded and reproduced as λ2 (nm), the relationship between the wavelength λ1 and the wavelength λ2 is set to be expressed by 10 ≦ |λ1 - λ2| ≦ 120. The first recording layer has a light absorptance ratio of at least 1.0 with respect to the wavelength λ1. The light transmittance of the first recording medium with respect to the wavelength λ2 is set to be at least 30 in both the cases where the recording layer is in a crystal state and in an amorphous state. In order to record and reproduce the optical multilayer disk with the above-mentioned characteristics, a multiwavelength light source with the following configuration is used. Wavelengths of fundamental waves with different wavelengths from injection parts formed at one end of a plurality of optical waveguides, which satisfy phase matching conditions different from one another and are formed in the vicinity of the surface of a substrate, are converted simultaneously, and the first and second laser beams are emitted from emission parts formed at substantially the same position at the other end of the optical waveguides. This enables an optimum optical system for high density recording and reproduction to be obtained.

摘要： A defect causing a localized state is induced in a chiral structure (12) composed of multiple chiral elements (20, 22) by twisting one element of the chiral structure with respect to the other elements along a common longitudinal axis such that directors of the element molecular layers that are in contact with one another at contact area (26) are disposed at a particular 'twist' angle therebetween, the twist angle being greater than a shift angle between directors of consecutive layers. The chiral twist structure may be utilized in a variety of applications such as filters, lasers and detectors. The defect caused by the twist may be made tunable by providing a tuning device for rotating one or more of the chiral elements with respect to one another to vary the twist angle and thus vary the position of the induced defect within a photonic stop band. Tunable defects may be advantageously utilized to construct tunable wavelength chiral filters, detectors and lasers.
