Systems and methods are described herein to thermally regulate laser diodes. During operation, the structure of a laser diode may generate heat, which will affect the stability and accuracy of the output wavelength of the laser diode. During an OFF stage, the structure of the laser diode will then lose heat, creating a thermal gradient as the laser diode is switched between operation and an OFF state. The systems and methods provide constant average heat and a stable thermal gradient by integrating a laser diode power-coupled supply and a heater onto a heatspreader, such that the output wavelength of a coupled laser diode may be stabilized.

Heater-on-heatspreader

The invention relates to a DFB laser diode having a lateral coupling, which comprises at least one semi-conductor substrate (), at least one active layer () that is arranged on the semiconductor substrate, at least one ridge () that is arranged above the active layer (), at least one periodic surface structure () that is arranged next to the ridge () above the active layer () and at least one wave guide layer () comprising a thickness &#x2267;1 &#x3bc;m that is arranged below and/or above the active layer.
