A technique for setting the absolute frequency of a 1.5 {mu}m two-section DBR laser using an Er:YAG optical filter as a frequency discriminator is described. The absolute frequency of the laser was controlled with an accuracy better than 300 MHz over a tuning range of several hundred gigahertz. The frequency drift with laser temperature was {minus} 130 MHz/{degrees}C and the tuning rate with current in the active region was 40 MHz/mA.
