Patent ID: 7133584

Claim:
An integrated broadband light source system comprising: a single monolithic chip, comprising A. a glass cladding layer deposited on a silicon substrate B. a coiled waveguide embedded in the cladding layer, wherein the waveguide is coiled into a loop having a first and a second input/outputs, and comprises dopants selected from the rare earth elements and transition metals at dopant levels where fluorescence is achieved and the fluorescent power overcomes total losses; C. a three-way splitter embedded in the cladding layer having one end connected to the first input/output of the coiled waveguide and having first splitter, second splitter, and third splitter input/outputs; and D. an optical coupler disposed at another portion of the coiled waveguide for coupling light into the coiled waveguide, wherein the optical coupler has one input/output and a second input/output.
