Abstract
The present invention relates to an optical module having a configuration in which centering adjustment can be effected much more easily than the prior art, while keeping a high optical coupling efficiency between an optical fiber and a semiconductor device, and can reduce the number of parts, for example; and a method of making the same. The optical module comprises, as an element for optically coupling the optical fiber and the semiconductor device together, an optical reflecting member having a concave reflecting surface. Since it is necessary for the reflecting member to be positioned with a high accuracy in the field of optical communications to which this optical module is supposed to be utilized, in particular, the reflecting member is provided with a specific positioning configuration.
