To develop the first monolithically integrated photonic heterodyne system capable of mutually phase locking two on-chip optical sources to an external optical reference.
Fabricated a monolithic photonic integrated circuit coupling two optical sources with an external reference input.
Integrated custom-designed fast loop electronics to minimize the signal propagation delay to less than 2 ns.
Demonstrated generation of high-spectral-purity signals reaching frequencies up to 50 GHz.
Identified optical losses within the input waveguide as the primary limitation on device tuning range.
Established that the integrated phase-locking architecture can be scaled to produce frequencies exceeding 1 THz.
