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.

Patent number: 11815725Abstract: An example photonic integrated circuit includes a transmitter circuit with a optical communication path to an optical coupler configured to couple with an optical fiber. The optical communication path has a propagation direction away from the transmitter circuit and towards the optical coupler. A counter-propagating tap diverts light sent by a light source backward against the propagation direction of the optical communication path. A photodiode receives the diverted light and measures its power level. The photodiode generates a feedback signal for the optical coupler and provides the feedback signal to the optical coupler. The optical coupler receives the feedback signal and adjusts a coupling alignment of the optical communication path to the optical fiber based on the feedback signal, which indicates the measured power level of the diverted counter-propagating light.Type: GrantFiled: December 17, 2021Date of Patent: November 14, 2023Assignee: OpenLight Photonics, Inc.Inventors: Brandon W. Buckley, Brian Robert Koch, John Garcia, Jared Bauters, Sudharsanan Srinivasan, Anand Ramaswamy
