  • Patent number: 11942997
    Abstract: Consistent with the present disclosure, a local oscillator is provided in a receiver. The local oscillator laser a first and second mirrors and phase section and heaters are provided adjacent each portion of the laser, such that the temperature and thus the frequency of light output from the local oscillator laser may be tuned. Applying electrical power, such as a current or voltage to the phase section may result in rapid frequency tuning of light output from the local oscillator laser but over a limited frequency range. Temperature changes to the mirror sections, however, may afford frequency tuning over a wider range, but frequency tuning the mirror sections requires more time than that required to tune the phase section. Consistent with the present disclosure, a tuning method and apparatus is provided that optimizes laser tuning by selectively tuning the phase and mirror sections.

  • Patent number: 11624880
    Abstract: An optical transceiver having a locking assembly that prevents undesirable movement of the optical transceiver when engaged with another device is described. The locking assembly includes a slide with a projection, lift, and weighted stops. In a first configuration, the slide and weighted stops can sustain contact between a thermal interface material of the optical transceiver and the other device while locking the optical transceiver to prevent movement. In a second configuration mode, the locking assembly disengages the thermal interface material from the other device and unlocks the weighted stops to permit disconnection from the other device.

  • Patent number: 6810173
    Abstract: An optical fiber amplifier system includes an optical fiber adapted for use as an optical wave guide amplifier, and at least one optical pump optically coupled into the optical amplifier, wherein the pump receives both a DC electrical input and an AC electrical input, and wherein the pump provides an optical pump power to the optical fiber having both a DC optical power component and an AC optical power component. The optical fiber amplifier system also includes an optical pump power detector optically coupled to the pump, and at least one controller operatively connected to the pump power detector to determine the DC optical power component of the optical pump power, and wherein the controller adjusts the DC electrical input to the pump based on the DC optical power component.
