Controller calibration methods for use with sampled grating distributed
Bragg reflector SGDBR laser (102) 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(102) to produce laser
setting data corresponding to each front mirror current setting and back
mirror current setting to generate a reference optical signal (114) of
the SGDBR laser (102). 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 (102) laser is generated from the operating point currents,
locker values and two-dimensional control surface data from each channel.
