An optical device includes: a first optical member having a light-exit end at which light exits the first optical member; a second optical member having a light-entrance end which abuts the light-exit end through a protective medium and from which the light enters the second optical member; and the protective medium which is arranged between the light-exit end and the light-entrance end, and suppresses fixing together of the light-exit end and the light-entrance end. Specifically, the protective medium is transparent and arranged between the light-exit end and the light-entrance end, and is reusable even after the light-exit end and the light-entrance end are pressed together with a pressure of approximately 0.5 or 1 kgf and are then separated from each other.

A laser module includes: a chassis having a light-output window from which one or more laser beams are outputted; a hermetically sealed package which is fixed to the chassis; one or more semiconductor laser elements which are arranged in the hermetically sealed package, and emit the one or more laser beams; a transparent member which is arranged to cover the light-output window; an optical fiber which has a light-entrance end face, and is arranged outside the chassis so that the light-entrance end face is in contact with the transparent member; and an optical condensing system which is arranged inside the chassis, and makes the one or more laser beams pass through the transparent member and be condensed on the light-entrance end face. The transparent member and the optical fiber are detachably attached to the chassis.

In a method for manufacturing an electronic device, a low melting point metal layer is provided to seal an electronic element between a pair of resin substrates each having a barrier layer laminated thereon. The low melting point metal layer bonds the barrier layers of the resin substrates to each other. The method includes the steps of: providing a light absorbing layer between at least one of the barrier layers and the low melting point metal layer; and irradiating a laser beam having a wavelength within a range from 350 nm to 600 nm onto the light absorbing layer through at least one of the resin substrates and the barrier layer laminated thereon, to heat and fuse the low melting point metal layer, thereby bonding the barrier layers to each other.

An organic EL panel comprises an element forming substrate, an organic EL element, which is formed on the element forming substrate, an adhesive layer, which is formed at a periphery of the element forming substrate so as to surround the organic EL element, and a sealing substrate, which is bonded to the element forming substrate through the adhesive layer. A hermetically sealing section, which is provided with low melting point metal layers, is formed at a position adjacent to the adhesive layer.

A large diameter fiber is composed of a multimode optical fiber and provided with a fiber body having a constant diameter in an optical axis direction XA and a tapered section tapered in diameter toward a light exit surface. An adhesive member attaches the large diameter fiber inside a retaining hole of a tubular housing such that an outer circumferential surface of a tapered clad of the tapered section is entirely exposed to air to a predetermined depth from the light exit surface. A light passing space is a ring-like space formed between the exposed outer circumferential surface of the tapered clad and an inner circumferential surface of the tubular housing. Light in the tapered section is output from the light exit surface and partially leaked to the tapered clad. A part of the leaked light is released from the light passing space.

An optical fiber structure includes a first fiber array and a second fiber array, which are placed one on the other. For example, the first fiber array includes a substrate having four V-shaped grooves and four first optical fibers, the output ends of which are linearly arranged and fixed to the substrate, and the second fiber array includes a substrate having four V-shaped grooves and four second optical fibers, the output ends of which are linearly arranged and fixed to the substrate. The first optical fiber is a multimode fiber having a core and a cladding, and the core diameter is 60 μm and the outer diameter of the fiber is 80 μm. The second optical fiber is a multimode fiber having a core and a cladding, and the core diameter is 105 μm and the outer diameter of the fiber is 125 μm.

An optical module in which the light outputted from the light source is condensed before outputted, and yet capable of reducing the development of contaminants on the light condensing area. The optical module includes: a light source for outputting light in the short wavelength region; a transparent member having a light input face and a light output face; and a condensing optical system for inputting the light outputted from the light source to the input face of the transparent member, and focusing the light on the output face. The transparent member has an alkali metal content (e.g. Na or K) of less than 2.0% by weight, and/or with a light absorption of less than 0.65%/mm for the light outputted from the light source.
