摘要： A discretely tunable laser device is provided. The discretely tunable laser device comprises: a laser comprising a plurality of discrete output modes; an optical filter for receiving output from the laser but otherwise optically isolated from the laser, the optical filter comprising a plurality of transmission peaks, each separated by a transmission spacing different from a spacing of the plurality of discrete output modes such that only one discrete output mode can predominantly align with one transmission peak when the plurality of discrete output modes are tuned; and, a control apparatus for tuning the discrete output modes of the laser to align a given output mode of the plurality of discrete output modes with a given transmission peak of the plurality of transmission peaks, such that the given output mode comprises a dominant output of the optical filter.

摘要： A method of reducing thermally-induced emission wavelength shift in laser diodes. In addition to the conventional ridge contact for supplying the modulation current to the laser diode a second ridge contact is formed on the device. A compensation current of substantially the same frequency as the modulation current but having an opposite phase is applied to the second contact. This compensation current is selected to substantially neutralize the transient temperature variations due to changes in the modulation signal and result in a generally steady state thermal situation.
