  • Publication number: 20150071315
    Abstract: A method and apparatus are described including a laser with a plurality of internal or external actuators for affecting an optical frequency of light output by the laser, wherein the plurality of actuators have a corresponding plurality of different frequency response bands for changing optical properties of the laser and a corresponding plurality of actuation ranges of optical frequencies affected. Also included is an optical detector, and a plurality of optical paths configured to direct light output by the laser onto the detector. A laser controller is configured to provide a plurality of inputs to the plurality of actuators based on a detector signal output from the optical detector and the corresponding frequency response bands and actuation ranges.

  • Publication number: 20120106579
    Abstract: A method, apparatus and computer-readable storage medium are described for a tunable laser source that produces a desired frequency modulated optical waveform with a precision within 0.01 percent over a bandwidth greater than about 50 gigaHertz. An apparatus includes a tunable laser having one or more drive inputs for affecting an optical frequency of light output by the laser; and an optical detector. Multiple optical paths are configured to direct light output by the laser onto the optical detector. A laser controller is configured to provide to a drive input a loopback signal based on a measured or predetermined difference in optical dispersion among the plurality of optical paths and a detector signal output from the optical detector. In some embodiments, a ranging device includes the tunable laser source.
