A wavelength-selective optical reception device includes a photoreceptor (21) that converts optical signals (201) into electric signals and outputs the electric signals, a base (31) on which the photoreceptor (21) is provided, a housing (41) that is mounted on the base (31) and surrounds the photoreceptor (21) along with the base (31), and that is provided with a window (51) to pass optical signals (203) including the optical signals (201) and including optical signals (202) of a wavelength different from a first wavelength of the optical signals (201) and a window (52) to pass the optical signals (202), and an optical filter (61) that is disposed inside the housing between the window (51) and the photoreceptor (21) along the optical axis (205) of the optical signals (203), and that outputs, out of the optical signals (203) that enter thereto, the optical signals (201) toward the photoreceptor (21), and reflects the optical signals (202) toward a near side in a direction of travel of the optical signals (203).

A method according to one embodiment includes steps of: preparing an optical module and optical fiber holding member; attaching a clip member to a receptacle of the optical module and the optical fiber holding member; and pressing the receptacle of the optical module and the optical fiber holding member from below and pressing the clip member from above. The pressing step has pressing the first flat surface of the receptacle and the second flat surface of the optical fiber holding member at the third flat surface of the clip member, and which performed until the first flat surface of the receptacle and the second flat surface of the optical fiber holding member establish parallelism with the third flat surface of the clip member by using a jig that changes the parallelism of the pressing surface.

Provided is an optical communication connector that includes a control unit (42). The control unit (42) controls alignment of a ferrule (170) and a lens (162). The ferrule (170) is to fix a fiber (23). The control unit (42) varies a shape of a shape variation member (21) on the basis of a communication quality of light entering the fiber (23) via the lens (162) to control the alignment.

An optical connection assembly joining optical components is described. The optical connection assembly is manufactured using a fan out wafer level packaging to produce dies/frames which include mechanical connection features. A fastener is joined to a connection component and affixed to the mechanical connection features, to provide structural support to the connection between the connected component and the die/frame structure.

A LED light apparatus includes a central beam module, a peripheral light module, a support housing and a cap. The central beam module has a beam lens for converting a first light to form a light beam. The peripheral light module has a light passing ring. The light passing ring surrounds the beam lens for converting a second light to form a peripheral light. The peripheral light has a lower intensity strength than the light beam. The support housing fixes the central beam module and the peripheral light module. The cap is fixed to the support housing for plugging in an external socket for getting an external power supply.

The present invention relates to a manufacturing method for an optical multiplexer provided with: a substrate having a first main surface and a second main surface that are parallel to each other; a mirror disposed on the first main surface; and an optical filter disposed on the second main surface.
