Abstract
A high dynamic range laser diode modulation scheme employs two laser diodes connected so that their outputs are added in a single optical fiber. The first diode is modulated over its dynamic range. The second diode is also modulated over its dynamic range, and is attenuated with a filter to provide fine level adjustment to the coarse levels provided by the first diode.
