摘要： A packaging platform for optically coupling one or more optical waveguides of one or more optical components having the optical waveguide to one or more optical fibers is provided with a reference structure portion for the horizontal and vertical positioning of the optical component. The platform is further provided with one or more fiber positioning portions for inserting and holding the optical fiber and positioning the optical fiber at a position where the optical fiber is optically connected to the optical waveguide. The provided packaging platform and an optical module using the platform can simplify all alignment steps for optical coupling, electrical connection and sealing in the coupling of the optical component and the optical fiber.

摘要： The ionizer of the present invention comprises a chamber which has an ionization part that ionizes a portion of an ion carrier gas that is supplied to the interior of this chamber, and a blowing part which feeds the ion carrier gas toward a charged body. The ionization part is constructed from an ionization source which is contained in the chamber, and a control device which is connected with this ionization source via a high-voltage cable. Either the generating part of a soft X-ray generating device, the generating part of a low-energy electron beam generating device or the generating part of an ultraviolet radiation generating device is used as the ionization source. The control device, the connecting part between the control device and the high-voltage cable and the connecting part between the ionization source and the high-voltage cable are formed with an explosion-proof structure.

摘要： A planar lightwave circuit type variable optical attenuator with a small polarization dependent loss is provided. By setting the waveguide birefringence (absolute value) in first and second optical coupler sections equal to or greater than 3.5×10−4, the polarization mode coupling is made equal to or less than −25 dB, and the effect of the polarization dependence caused by the polarization mode coupling at the cross port of the first and second optical couplers is suppressed. In addition to or independently of this, the arm waveguide length can be designed to be equal to an integer multiple of the optical beat length obtained by dividing a used optical wavelength by the waveguide birefringence.

摘要： This planar lightwave circuit includes a buried layer formed in a region between at least two cores branching from a branching point to decrease in thickness as the spacing between the cores increases with an increase in distance from the branching point. The planar lightwave circuit is designed to suppress scattering of light signals at the branching point.

摘要： An integrated optical device includes a substrate; a single-mode optical waveguide having a cladding layer disposed on the substrate and a core portion embedded in the cladding layer for transmitting light therethrough; and a stress applying film disposed on a desired portion of the cladding layer for adjusting stress-induced birefringence of the single-mode optical waveguide by irreversibly changing the stress exerted on the core portion by a trimming technique. The integrated optical device can be manufactured by the steps of forming a cladding layer on a substrate; forming a single-mode optical waveguide having a core portion embedded in the cladding layer for transmitting light therethrough; and forming, on the cladding layer, a stress applying film for exerting a stress on the single-mode optical waveguide to irreversibly change the stress by trimming the film. The device exhibits a precisely adjusted birefringence and a desired polarization dependence or independence, and is effective for constructing an integrated optical device for optical communication, for optical sensing or for optical signal processing, in which the polarization characteristics play an important role.
