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.
Claims21
A transmitter optical sub-assembly (TOSA) laser package comprising:
- a laser package support structure including a TOSA housing defining a laser package region;
- a semiconductor laser supported by the laser package support structure and enclosed within the TOSA housing, the semiconductor laser being configured to generate light output in response to electrical input;
- a memory device supported by the laser package support structure and enclosed within the TOSA housing such that the memory device is inside the TOSA package, the memory device being configured to store parameter data representing parameters associated with the semiconductor laser;
- and
- conductive paths extending from the laser package support structure to the exterior of the TOSA package, the conductive paths including at least one laser input path configured to receive the electrical input to the laser and at least one memory data path configured to carry the parameter data.
