Method and apparatus for the operation of a distributed feedback laser
Patent
·
OSTI ID:5705517
This patent describes an optical apparatus of the type including a distributed feedback semiconductor laser having a stop band in which laser oscillations are inhibited and beyond which laser oscillations can occur, the laser having controllable excitation biasing for two axially distinct portions of a path along which oscillations occur in the laser. The apparatus being characterized by means periodically varying the excitation biasing of one of the portions with respect to the excitation biasing of the other of the portions for controllably switching the laser oscillations across the stop band.
