Abstract:
1. A microphotonic light source comprising: an optical pump; a plurality of waveguides that distribute optical pump power of said optical pump, said waveguides comprising silicon nitride (Si a plurality of Erbium-doped laser ring structures that are coupled to at least one of said waveguides, each of said Erbium-doped laser rings having radial dimensions designed to match the resonance condition for both said optical pump and associated wavelengths, said Erbium-doped laser ring structures comprising Erbium-doped Si a plurality of undoped routing ring structures aligned along a principal waveguide bus to distribute the power from the optical pump to regions comprising said Erbium-doped laser ring structures; wherein said Erbium-doped laser ring structures and said undoped routing ring structures are of varying dimensions and act as selective pump routers and signal filters.
