Abstract

Provides an optical module capable of achieving both miniaturization and tracking error suppression. A temperature control module (4) is fixed on the tube base (7), and a support (3) is fixed on the temperature control module. A light emitting element (1) is fixed to the support, signal light is emitted from the front surface (1b) of the light emitting element, and back light is emitted from the rear surface (1c). In addition, a light receiving element (2) is fixed to the support. In addition, a reflective surface (3a) is provided on the support. The light-receiving element has a light-receiving surface (2b) for receiving back light reflected by the reflecting surface (3a), and the center of the light-receiving surface is arranged to be located between the front surface (1b) and the rear surface of the light-emitting element (1) in the direction of the optical axis of the signal light. between surfaces (1c). The lens cover (5) is fixed on the socket (7) in such a way that the temperature control module (4), the support (3), the light emitting element (1) and the light receiving element (2) are covered inside, and the lens cover (5) A lens (6) for receiving signal light is fixed.

Description

technical field [0001] The present invention relates to an optical module used in the field of optical communication and the like. Background technique [0002] For an optical module using a temperature control module for controlling the temperature of a light-emitting element, a TO-CAN (Transistor Outlined CAN) type package can be used in order to meet the demand for downsizing. In order to reduce the tracking error of the above-mentioned optical module, Patent Document 1 discloses a structure in which one lens is added. In addition, Patent Document 2 discloses a structure using a permeable member that expands or contracts with a temperature change. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2011-108937 [0004] Patent Document 2: Japanese Patent Laid-Open No. 2014-132627 [0005] In the above-described conventional example, since additional components such as lenses and transmissive members are required, and space for disposing these components must be se...
