Abstract: In accordance with the present invention, one or more laser diodes are efficiently coupled into a waveguide amplifier in order to provide either an efficient amplifier or a laser. Light from one or more laser diodes is efficiently coupled into one or more waveguides through the effects in the refractive index between the core material of the waveguide and the cladding material around the waveguide. Both the core material and the cladding material can be deposited with a high degree of uniformity and control in order to obtain the coupling.

Abstract: Planar wave guide devices deposited by reactive pulsed dc sputtering processes are presented. Devices according to the present invention include a waveguide with a core sputter deposited onto a substrate and a cladding sputter deposited onto the core. In some embodiments, second waveguide can be deposited in close proximity to the first waveguide to form a direction coupler. In some embodiments, light traveling through the waveguide can be amplified or attenuated in response to signals applied to the waveguide. In some embodiments, a DWDM device is formed in the waveguide. In other devices, a mode-locked laser is formed.
