Abstract
PURPOSE:To prevent falling of a bar-shaped semiconductor laser from a jig for forming the end-surface protecting film of the semiconductor laser and to prevent the formation of the protecting film on the entire surface of the electrode of the semiconductor laser, by attaching a spacer between the bar- shaped semiconductor laser and a cover. CONSTITUTION:A bar-shaped semiconductor laser 103 is coupled into the groove part of a base 101 so that an active layer 104 is positioned at the upper side. A spacer 107 comprising single crystal silicon is coupled from the upper side and fixed with a cover 102. A part of an electrode 105 is exposed from the spacer 107. The upper part of the groove is widely formed so that an evaporating agent for protection is sufficiently applied to an end surface 106 of a resonator. In this way, the upper side of the bar-shaped semiconductor laser 103 is pushed with the spacer 107, which is slightly narrower than the width of the bar-shaped semiconductor laser, and the spacer 107 is fixed with the groove at both end parts of the base 101. Therefore, the bar-shaped semiconductor laser 103 does not fall out of the jig, and the protecting film is not formed on the entire surface of the electrode 105.
