Abstract
The present invention relates to an optical module with a small size and improved mass-productivity. The optical module comprises a fiber stub including an optical fiber, a sleeve containing the fiber stub, and a semiconductor optical amplifying device. A Bragg fiber grating is formed in the optical fiber. The optical fiber is secured in the ferrule. The optical amplifying device and the grating form a laser cavity. Only a part of the hollow portion of the sleeve is filled with the fiber stub. One end face of the optical fiber is disposed at one end of the sleeve. The other end of the sleeve is hollow. The optical module acts as an optical receptacle. An optical plug can be inserted into the hollow end of the sleeve. This enables the laser light to be introduced into an external optical device.
