Patents by Inventor Ruud Michiel OLDENBEUVING

Ruud Michiel OLDENBEUVING has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20220365376
    Abstract: The instant disclosure is directed toward integrated-optics-based composite phase controllers that include at least one thermo-optic (TO) phase controller and at least one stress-optic (SO) phase controller, each of which is configured to affect the phase, or other propagation characteristic, of a light signal travelling through a surface waveguide. The SO phase controller can induce a small phase change quickly, while the TO phase controller can slowly induce a larger phase change. Embodiments are particularly well suited for use in waveguide-based resonant elements, such as ring resonators, spectral filters, and the like. Furthermore, photonic systems comprising one or more composite phase controllers can be developed, such as wavelength-tunable lasers for applications such as LiDAR, chemical/biological sensing, medical diagnostics, and optical communications.

  • Patent number: 11489611
    Abstract: An approach for realizing low-power, high-port-count optical switching systems, such as OXCs, WXCs, and ROADMs is presented. Optical switching systems in accordance with the present disclosure include arrangements of frequency-filter blocks, each of which includes a cascaded arrangement of tunable couplers and tunable Mach-Zehnder Interferometers (MZIs) that provides a substantially flat-top broadband transfer function for the frequency-filter block. The tunability for these devices is achieved by operatively coupling a low-power-dissipation phase controller, such as a stress-optic phase controller or liquid-crystal-based phase controller with one arm of the device, thereby enabling control over the coupling coefficient of the device.

  • Patent number: 11320587
    Abstract: Aspects of the present disclosure describe planar lightwave circuit systems, methods and structures including a resonant mirror assembly having cascaded resonators that provide or otherwise facilitate the control of the transmissivity/reflectivity of a planar lightwave circuit (PLC)—or portion thereof—over a range of 0% to substantially 100%.

  • Publication number: 20220131342
    Abstract: Aspects of the present disclosure describe systems, methods and structures including an integrated-optics-based externa-cavity laser configured for mode-hop-free wavelength tuning having an increased continuous tuning range with an ultra-narrow linewidth by increasing tuning sensitivity. Ultra-narrow linewidth is provided by extending cavity length with a multi-pass resonator based filter that may advantageously include tunable microring resonators that enable single-mode oscillation while contributing to the optical length of the laser with multiple passes of light through the ring(s) per roundtrip in the laser cavity. Further aspects of the present disclosure describe systems, methods, and structures exhibiting an enhanced “tuning sensitivity”—defined by a continuous wavelength shift per induced cavity phase shift by a phase section. Such tuning sensitivity is increased by approximately a factor of 3 for synchronous tuning of phase section and ring resonators as compared to tuning phase section only.
