  • Publication number: 20240090102
    Abstract: Disclosed herein is an integrated photonics device including a frequency stabilization subsystem for monitoring and/or adjusting the wavelength of light emitted by one or more light sources. The device can include one or more selectors that can combine, select, and/or filter light along one or more light paths, which can include light emitted by a plurality of light sources. Example selectors may include, but are not limited to, an arrayed waveguide grating (AWG), a ring resonator, a plurality of distributed Bragg reflectors (DBRs), a plurality of filters, and the like. Output light paths from the selector(s) can be input into one or more detector(s). The detector(s) can receive the light along the light paths and can generate one or more signals as output signal(s) from the frequency stabilization subsystem.

  • Patent number: 7509049
    Abstract: A method and apparatus are provided for transferring a plurality of satellite signals through an optical communication network. The method includes the steps of selecting a frequency of a local oscillator signal within a guardband between a left polarization signal and a right polarization signal of a first satellite signal of the plurality of satellite signals, frequency shifting the first satellite signal upwards in frequency by the selected frequency. The method further includes the steps of combining the frequency shifted satellite signal with a second satellite signal of the plurality of satellite signals and modulating a optical carrier with the combined signals, transferring the modulated optical carrier to a receiver through an optical fiber and decoding the first and second satellite signals within the receiver.
