ABSTRACT:
A modulatable laser diode for high frequencies, such as a tuneable turn guide distributed feedback laser diode, that has a central layer provided for a separate current supply located between a tuning layer and an active layer. The tuning layer has a quantum well structure. A ridge waveguide is provided for the laser diode and the layer sequence is limited to a strip-shaped mesa on the substrate in order to reduce the parasitic capacitances.
