Abstract
The present application is directed to a waveguide amplifier. The waveguide amplifier has a substrate including an upper surface and a lower surface. The waveguide amplifier also has a core made of silicon or silicon nitride formed on an upper surface of the substrate. The core includes a channel configured to transmit light there through. The waveguide amplifier also includes an upper cladding layer formed above the core. The upper cladding layer includes a glass doped with rare earth material. The application is also directed to a method of amplifying a signal.
