Abstract
An optical device comprises a Praseodymium (Pr)-dope waveguide optical amplifier capable of amplifying O-band light. The waveguide optical amplifier may be formed on the substrate (e.g., silicone or glass) and comprises a core defining an optical path through the waveguide optical amplifier, and cladding abutting at least one side of the core. The core comprises a silicon-based material, such as silicon nitride (Si3N4), doped with Praseodymium (Pr) such that, on condition of pump light and O-band signal light being passed through the waveguide optical amplifier, the waveguide optical amplifier amplifies the O-band signal light.
