Abstract
A solid-state optical amplifier chip is described, with improved pumping, in which pump light from one or more solid-state light sources is coupled efficiently into the doped areas of the chip, resulting in amplification of an optical signal. The optical signal is carried in the core of an optical waveguide. Rare-earth elements are used as dopants, primarily in the cladding of the optical signal's waveguide core, in order to provide amplification of the optical signal through stimulated emission. A variety of waveguide structures are described for routing and distributing the pump light to the doped areas of the chip.
