Wavelength Locking

You can choose wavelength locking as the modulation source, so
the output wavelength is proportional to the voltage you apply to
the input BNC connector on the front panel of your Tunable Laser
module as shown in Figure 5-16. See Appendix C of the Tunable
Laser Modules User's Guide for the conversion factor for each
Tunable Laser module.
