Patent number: 11909516Abstract: Embodiments of the invention describe apparatuses, optical systems, and methods for utilizing a dynamically reconfigurable optical transmitter. A laser array outputs a plurality of laser signals (which may further be modulated based on electrical signals), each of the plurality of laser signals having a wavelength, wherein the wavelength of each of the plurality of laser signals is tunable based on other electrical signals. An optical router receives the plurality of (modulated) laser signals at input ports and outputs the plurality of received (modulated) laser signals to one or more output ports based on the tuned wavelength of each of the plurality of received laser signals. This reconfigurable transmitter enables dynamic bandwidth allocation for multiple destinations via the tuning of the laser wavelengths.Type: GrantFiled: May 4, 2022Date of Patent: February 20, 2024Assignee: Juniper Networks, Inc.Inventors: Brian Robert Koch, Daniel Sparacin, Alexander W.

Publication number: 20050013575Abstract: The light-guiding structure includes a waveguide structure that comprises a substrate and a low refractive index underclad material. The waveguide structure is oxidized to form an oxidized layer on a surface of the waveguide structure. The oxidized layer is isotropically etched after the reaction-limited oxidation regime is approaching the diffusion-limited regime and repeatedly oxidized and etched so that the waveguide structure is continuously oxidized in the reaction-limited regime, reducing the overall time of oxidation and volume of oxidized material so that the waveguide structure has its sidewall roughness reduced efficiently enabling high transmission rates of guided light.Type: ApplicationFiled: June 16, 2004Publication date: January 20, 2005Inventors: Daniel Sparacin, Kazumi Wada, Lionel Kimerling
