Abstract
A multistage optical amplifier includes a fiber amplifier stage having an active optical fiber for imparting gain to an optical signal propagating therethrough and a coupler supplying pump energy to the optical fiber. A planar waveguide amplifier stage is optically coupled to the fiber amplifier stage. The waveguide amplifier including a substrate, an active planar waveguide formed on the substrate for imparting gain to an optical signal propagating therethrough, and at least one waveguide coupler formed on the substrate for coupling pump power to the active planar waveguide.
