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.
Claims26
An arrangement including:
- a semiconductor laser structure including a laser active region having at least one side trench extending along said laser active region, and
- a heatable element arranged in said at least one side trench so as to be in heat transfer relation with the laster active region, the heatable element being adapted to be powered by an energy source for heating the heatable element and for causing the laser active region to be at a desired temperature.
