  • Laser package including semiconductor laser and memory device for storing laser parameters
    Patent number: 8787772
    Abstract: A laser package may include a semiconductor laser and a memory device integrated into the laser package for storing parameters associated with the laser. The parameters may include laser manufacturing, operational and/or user parameters. For example, the semiconductor laser may be tunable and the memory device may store tuning parameter data. One example of the laser package is a tunable transmitter optical sub-assembly (TOSA) package.

  • WAVELENGTH LOCKER AND LASER PACKAGE INCLUDING SAME
    Publication number: 20090310635
    Abstract: A wavelength locker may include a first optical detector configured to detect light, wherein the first optical detector is at least partially transparent to the light. The wavelength locker may further include an optical interferometer optically coupled to the first optical detector and to a second optical detector. The optical interferometer is configured to selectively filter the light that passes through the first optical detector and the second optical detector detects the filtered light. An optical module or package may include the wavelength locker coupled to a laser for locking an emission wavelength of the laser.
