Abstract
Controller calibration methods for use with sampled grating distributed Bragg reflector SGDBR laser () is presented. An exemplary method includes conducting a two-dimensional mirror current scam of each front mirror current setting and back mirror current setting for a sampled grating distributed Bragg reflector SGBDR laser() to produce laser setting data corresponding to each front mirror current setting and back mirror current setting to generate a reference optical signal () of the SGDBR laser (). A channel operating point is determined for each channel within the two-dimensional scan data. A fix up of the operating point to substantially minimize wavelength and power error can also be performed. A two-dimensional control surface is characterized at the channel operating point for each channel. A lookup table for controlling the SGDBR () laser is generated from the operating point currents, locker values and two-dimensional control surface data from each channel.
