Abstract
A semiconductor laser structure has a laser active region and side trenches extending along the laser active region. At least one heatable stripe, in at least one of the side trenches, is connected to an electric power source. The amount of energy the source supplies to the stripe controls the laser active region temperature to control and offset effects of active region temperature on the emitted wavelength.
