摘要	In addition to the optically passive alignment between the optical fiber and the semiconductor device using a V-groove provided on a substrate made of silicon single crystal, the active alignment therebetween may be carried out for enhancing the optical coupling efficiency. According to the present invention, the optical module provides a coupling member including a center waveguide and a sheath member covering the center waveguide. The outer shape of the sheath member is an elliptic so that the center position of the center waveguide may move as the coupling member rotates in the V-groove such that the outer surface thereof touches two sides of the V-groove. Accordingly, the optical coupling efficiency with the semiconductor device may be varied. The ellipticity of the elliptic outer shape is preferably greater than unity and not greater than 2, and the bottom angle of the V-groove is preferably not smaller than 60° and not greater than 120°, in particular, the angle is preferably a right angle in substance.
其他摘要	除了使用设置在由硅单晶制成的基板上的V形槽的光纤和半导体器件之间的光学无源对准之外，可以执行它们之间的有源对准以提高光学耦合效率。根据本发明，光学模块提供包括中心波导和覆盖中心波导的护套构件的耦合构件。护套构件的外形是椭圆形，使得中心波导的中心位置可以随着联接构件在V形槽中旋转而移动，使得其外表面接触V形槽的两侧。因此，可以改变与半导体器件的光学耦合效率。椭圆形外形的椭圆率优选大于1且不大于2，并且V形槽的底角优选不小于60°且不大于120°，特别地，该角度优选为右实质上的角度。
