Abstract
An optical semiconductor device includes a chassis that has an external wall, a feedthrough that penetrates the external wall of the chassis and has a projection portion projecting toward outside of the chassis from the external wall, a connection terminal that is electrically connected to a component mounted in the chassis and is on the projection portion of the feedthrough, a first temperature detector that is on an external face of the external wall of the chassis and detects a temperature of the chassis, and a flexible substrate of which an end is connected to the connection terminal and of which a portion spaced from the end is connected to the first temperature detector, wherein the first temperature detector is between the external wall and the flexible substrate.
Claims5
An optical semiconductor device comprising:
- a chassis that is a parallelepiped shape and has an external wall;
- a feedthrough that penetrates the external wall of the chassis and has a projection portion projecting toward outside of the chassis from the external wall;
- a connection terminal that is electrically connected to a component mounted in the chassis and is provided on the projection portion of the feedthrough;
- a plurality of lead pins that are provided on the connection terminal on the projection portion;
- a first temperature detector that is provided on an external face of the external wall of the chassis and detects a temperature of the chassis;
- and
- a flexible substrate of which a first portion is electrically connected to the connection terminal via the lead pins and of which a second portion spaced from the first portion is connected to the first temperature detector,
- wherein the plurality of the lead pins are projecting to outside of the projection portion of the feedthrough and projecting from the first portion of the flexible substrate, and
- wherein the first temperature detector is provided between the external wall and the flexible substrate.
