摘要： A transmission grating that provides low polarization dependent loss over a wide wave range and provides high diffraction efficiency even with a small groove pitch and high resolving power and dispersion. In a transmission grating 10, multiple parallel ridges 22 that are transparent for the wave range to be used are disposed on one side of a substrate 20 that is transparent for the wave range to be used. Parallel grooves 24 are formed at a fixed pitch a between these ridges. Light is applied from the surface of the transmission grating on which the grooves are formed and diffracted light is extracted from the substrate surface on which grooves are not formed. The groove pitch a is set to a range of 0.51 λc-1.48 λc, where λc is the central wavelength.

摘要： It is a collimator adapted to convert divergent light beams outputted from an optical fiber bundle to parallel light beams through a collimator lens. A large diameter optical fiber is disposed between an optical fiber bundle, which is a bundle of a large number of multimode optical fibers and serves as one optical transmission path, and a collimator lens. A cross-section of the core of the large diameter optical fiber is larger than a range in which the cores of the optical fibers of the optical fiber bundle are present. Also, a group of divergent light beams outputted from the optical fibers of the optical fiber bundle is converted by the large diameter optical fiber to one light beam.

摘要： A transmission diffraction optical element is presented in which ridges having a roughly rectangular cross-section shape are disposed parallel to each other at a regular pitch at the surface of a substrate. Striped thin-film layers are formed on these ridges and a thin-film layer is inserted between the substrate and the ridges. The thin-film layers are arranged at a regular pitch identical to the regular pitch of the ridges and the thin-film layer does not have a periodic pattern oriented in the same direction as the periodic pattern of the ridges.
