Summary: | An optical amplifier comprises a substrate, an optical multiplexer embedded in the substrate, pump light sources with multiple wavelengths coupled to the optical multiplexer, and an amplification waveguide coupled to the multiplexer. In one embodiment an optical signal is directed to another waveguide in the substrate. In another embodiment, the amplification waveguide is doped with a rare earth element. |
