Embodiment Construction

[0017] 〔Structure of optical equipment〕

[0018] refer to figure 1 The structure of the optical device 1 according to one embodiment of the present invention will be described. exist figure 1 (a) is a top view of the optical device 1, figure 1 (b) is a sectional view of the optical device 1 . also, figure 1 The sectional view shown in (b) is figure 1 The arrow view of the AA' section shown in (a).

[0019] Such as figure 1 As shown, the optical device 1 includes an optical fiber OF, a heat sink 11 , a heat conductor 12 , a support 13 , a resin body 14 , an adhesive 15 , and an adhesive 16 . In addition, although the heat conductor 12 and the support body 13 are members provided on the upper surface of the heat sink 11, they are mutually independent members.

[0020] The optical fiber OF is an optical fiber in which two optical fibers are fused, and includes a fusion point. The vicinity of the melting point of the optical fiber OF constitutes the coating removal ...

Abstract

The present invention implements an optical device capable of suppressing an increase in the temperature of an optical fiber while ensuring mechanical reliability. An optical device (1) includes a thermal conductor (12), a support (13), and an optical fiber (OF). The support (13) is separated from the thermal conductor (12) and has a smaller thermal expansion rate than the thermal conductor (12).The optical fiber (OF) is brought into thermal contact with the thermal conductor (12) via a resin body (14) covering a stripped section (Ia), and is secured to the support (13) in each of two coatingsections (Ib1, Ib2).

Description

technical field [0001] The present invention relates to an optical device including an optical fiber provided with a coating-removed section, and a reinforcing structure for reinforcing the coating-removed section. Background technique [0002] A coating removal section is often provided in an optical fiber. The coating removal section refers to a section of the optical fiber in which the resin coating is removed and the glass cladding is exposed. For example, when two optical fibers are fused, a coating removal section is provided near the fusion point. In addition, a coating removal section is also provided in a cladding mode separator for removing cladding mode light from an optical fiber. [0003] The coating-removed section is inferior in mechanical strength compared to other sections. Therefore, various reinforcement structures for reinforcing the coating removal section have been employed. As documents disclosing the reinforcement structure of the coating removal ...
