  • Coupling modulated ring resonator modulator
    Patent number: 11953800
    Abstract: An optical resonant modulator based on coupling modulation, comprising a resonant structure with an embedded Mach-Zehnder interferometer that is differentially driven to induced amplitude modulation at the output port. The principle of coupling modulation enables high data/baud rates to be achieved in a photonic integrated circuit, e.g. silicon, footprint that is considerably smaller than that of a conventional traveling-wave Mach-Zehnder modulator, in particular by utilizing space saving features, such as ring resonator phase shifters and bend waveguide arms.
    Type: Grant
    Filed: February 9, 2022
    Date of Patent: April 9, 2024
    Assignee: Nokia Solutions and Networks Oy
    Inventors: Ajay Mistry, Meisam Bahadori, Alexander Rylyakov, Rafid Sukkar, Matthew Streshinsky
