| 英文摘要 | An optical amplifier with at least one high reflectivity facet oriented at a nonperpendicular angle to the amplifier's waveguide to couple light vertically through a top or bottom surface of the amplifier. Angled facets could be at just one end of the waveguide or at both ends of the waveguide. In the latter case, the facets can be approximately parallel to or perpendicular to each other for respective coupling to opposite or same sides of the amplifier. Multiple amplifiers can be formed end-to-and with v-grooves defining the angled facets or can be formed side-by-side with parallel waveguides. Waveguides can also branch to form a 1:2, 1:4 or 2:2 optical signal multiplier or optical switch depending on whether just one or all of the waveguide branches are electrically pumped. Fibers are coupled to the amplifier receiving and emitting surfaces. Angling the fiber end with respect to the surface prevents reflections from feeding back into the amplifier waveguide. The facets can also be oriented at an angle other than 45 degrees to direct the light out of the surface at a nonperpendicular angle. |
