Embodiment approach 1

[0033] Hereinafter, embodiments of the present invention will be described in detail.

[0034] (Outline description of the optical element module 101)

[0035] figure 1 It is a cross-sectional view of the schematic structure of the optical element module 101 of this embodiment.

[0036] like figure 1 As shown, regarding the optical element module 101, an optical element (element having an optical function) 1 is mounted on the bottom surface 11b of a package body (casing) 11 made of metal, including an opening for blocking the package body 11 and A cover 12 that seals the optical element 1 inside.

[0037] As the optical element 1, an element having an optical function such as a reflective function, a light receiving function, or a light emitting function is used. In addition, in this embodiment, although an LCOS (Liquid Crystal On Silicon: liquid crystal on silicon) element is used as a reflective element (reflective optical switch element) as the optical element 1, the el...

Embodiment approach 2

[0059] Other embodiments of the present invention will be described below. In addition, components having the same functions as those in the above-mentioned embodiment are given the same reference numerals, and detailed description thereof will be omitted.

[0060] (Outline description of the optical element module 102)

[0061] figure 2 It is a cross-sectional view of the schematic structure of the optical element module 102 of this embodiment.

[0062] figure 2 The illustrated optical element module 102 differs from the optical element module 101 of the first embodiment in the following two points. That is, the first difference is that the optical element (element having an optical function) 1 is mounted on the bottom surface 11 b of the package main body 11 via the base 14 , and the second difference is that the polyurethane 13 is pasted on the surface of the optical element 1 . The bottom surface 11b of the package main body 11 facing the back surface 1a.

Abstract

Provided is an optical element module in which a foreign substance and water remaining in the module can be adsorbed and absorbed with a simple configuration requiring no complicated manufacturing step. This optical element module (101) having an optical element 1 mounted in a sealed housing (11, 12) has self-adhesiveness. Polyurethane (13) having a predetermined shape is fixed in the optical element module (101) by the self-adhesiveness.

Description

technical field [0001] The present invention relates to an optical element module in which an optical element is mounted in a sealed case and a method for manufacturing the same. Background technique [0002] Generally, an optical element module (hereinafter referred to as a module) in which an optical element (element with optical function: LD: Laser diode, laser diode or LED: light-emitting diode, light-emitting diode) is mounted in a sealed case has the following structure , comprising: a casing; an optical element installed in the casing; and a cover with a window for transmitting light, and sealed with dried inert gas. [0003] In such a module, there is a problem that foreign matter (about 15 μm in diameter) and moisture mixed into the module adversely affect the optical element. For example, when the above-mentioned foreign matter exists on the optical path of light incident on or emitted from the optical element, it will prevent the optical element from exhibiting e...
