Latest Patents

Dimitri's latest patents showcase his expertise in integrated-optics technology. One notable patent is for an "Integrated-optics-based composite phase controller operative for thermal-based and stress-based phase tuning of a surface waveguide." This invention introduces innovative composite phase controllers that utilize both thermo-optic (TO) and stress-optic (SO) mechanisms. The SO phase controller is designed for rapid phase changes, while the TO phase controller allows for more gradual, larger phase shifts. This technology is particularly beneficial for waveguide-based resonant elements such as ring resonators and spectral filters, and it has potential applications in wavelength-tunable lasers for LiDAR, chemical/biological sensing, medical diagnostics, and optical communications.

Another significant patent is for an "Integrated-optics-based external-cavity laser configured for mode-hop-free wavelength tuning." This invention describes a system designed to achieve an increased continuous tuning range with an ultra-narrow linewidth. The innovation is realized through a multi-pass resonator-based filter that incorporates tunable microring resonators. This design ensures that single-mode oscillation occurs while multiple light passes through the rings, enhancing tuning sensitivity by approximately three times when phase sections and ring resonators are tuned synchronously.
