Abstract:
1. A side-coupling optical fiber assembly comprising: a first substrate having at least one groove formed on one of its surfaces; an optical fiber arranged in the groove; and a second substrate arranged above the first substrate such that the second substrate presses and covers the optical fiber, wherein the first and the second substrates are fixed together; wherein an inclined facet is formed on the fiber end positioned between the first and the second substrates, the inclined facet being for realization of a total internal reflection of the light beam transmitted in the optical fiber, and wherein one end edge facet of each of the first and second substrates is in the same surface of the inclined facet of the optical fiber, wherein the end edge facet of the second substrate extends along the entire edge of the second substrate, and wherein the end edge facet of the second substrate includes an alignment guide edge on the upper surface of the second substrate; wherein a first light-passing hole is arranged in the second substrate, the first light-passing hole corresponding to the path of the light beam after the light beam is totally reflected from the inclined end facet of the optical fiber, or wherein the second substrate is made of an identical material as that of the waveguide of the optical fiber; wherein the second substrate is an extended optical bench and at least one optical element is arranged on the second substrate, and alignment of the optical element on the second substrate is based upon the alignment guide edge on the upper surface of the second substrate.
