Abstract

A method and apparatus for precisely calibrating a digitally controllable current driver (10,100) is described. The current driver to be calibrated is used to drive a semiconductor laser (30,300) and an optical parameter of laser light emitted from the semiconductor laser is measured. The current driver is replaced by a calibrated current source (70, 700) to drive the laser so that the laser emits laser light with the previously measured optical parameter, and the current supplied by the calibrated current source recorded thereby providing a calibration point for the current driver. The invention has particular applicability to current drivers for driving tunable multi-section semiconductor lasers.
