Abstract:
An optical module, comprising:a first optical fiber; a first lens, optically coupled with the first optical fiber, for receiving an incident light from the first optical fiber and converting the incident light into a parallel light; an optical device for receiving the parallel light and performing predetermined optical processing on the parallel light; a second lens for receiving a transmitted parallel light from the optical device and converging the transmitted parallel light to produce an outgoing light; a second optical fiber, optically coupled with the second lens, for receiving the outgoing light; wherein an optical axis of the first lens and an optical axis of the second lens are substantially coincident with each other, and an optical axis of the first optical fiber and an optical axis of the second optical fiber are substantially parallel with each other and substantially parallel to the optical axes of the first and second lenses; wherein adjustments of a vertical oblique angle with resnect to the optical axis of the first lens and a horizontal oblique angle with respect to the optical axis of the first lens are omitted respectively for the first optical fiber, wherein adjustments of a vertical oblique angle with respect to the optical axis of the second lens and a horizontal oblique angle with respect to the optical axis of the second lens are omitted respectively for the second optical fiber, wherein each of the vertical oblique angle &thgr;x and the horizontal oblique angle &thgr;y of the first optical fiber with respect to the optical axis of the first lens is set within 0.2 degrees, and wherein each of the vertical oblique angle &thgr;x and the horizontal oblique angle &thgr;y of the second optical fiber with respect to the optical axis of the second lens is set within 0.2 degrees.
