Embodiment Construction

[0030] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] figure 1 It is a perspective view of a schematic structure of a light transmitter device (light transmitter device) 1 according to an embodiment of the present invention. figure 2 show figure 1 The cross-sectional structure of the optical transmitter. figure 1 and 2 are schematically shown configurations, and may differ from actual sizes or shapes.

[0032] The optical transmission device 1 of this embodiment is generally called TOSA (Transmitter Optical Sub Assembly, optical transmission sub-assembly), which converts an externally input electrical signal into an optical signal and outputs the optical signal. The light transmitting device 1 includes, for example, a stem 10 , a light emitting element 20 , a light receiving element 30 , a cap 40 and a lens housing 50 . The stem portion 10 corresponds to a specific example of the "bas...

Abstract

An optical device and a method of making an optical device is described herein. The optical device comprises a housing, an optical element, a base structure that supports the optical element and that interfaces with the housing to form a gap section between an outer wall section of the base structure and an inner wall section of the housing, a resin within the gap section fixing the housing to the base structure, and a light accommodation section in the housing. The light accommodation section accommodates a transmittance of light to the resin within the gap section.

Description

technical field [0001] The present invention relates to an optical device having a transmitting function of converting an electrical signal into an optical signal and outputting the optical signal, or a light receiving function of converting an optical signal into an electrical signal and outputting the electrical signal, and a manufacturing method thereof. Background technique [0002] In the XFP (10-Gibabit Small Form Factor Pluggable, 10Gb Small Form Factor Pluggable) module, which is the standard for optical receiving / transmitting modules, an optical device is installed, which includes an optical device that converts electrical signals into optical signals and outputs optical signals. A transmitting device, or a light receiving device that converts an optical signal into an electrical signal and outputs the electrical signal. In this optical device, for example, a light-emitting element or a light-receiving element is mounted on the top surface of a stem (stem) and seale...
