In an optical module (1), an optical fibre (6) has an end (9) aligned with a semiconductor laser diode (10), such that light is coupled from a lasing portion of the diode (10) into the optical fibre (6). The laser diode (10) is mounted on a heatsink (8), which is itself mounted on a component portion (13) of a submount (11). The optical fibre (6) is mounted on a fibre attachment element (12), which is mounted on the component portion (13) of submount (11) in order to maintain the laser diode and the optical fibre in alignment. The submount (11) is mounted on an inner surface of the housing (2) by a fixing portion (14) leaving the component portion (13) of the submount (11) free of the housing (2), such that mechanical stresses in the housing (2) are not transmitted to the component portion (13) of the submount (11). <IMAGE> |
