ABSTRACT
We demonstrate wavelength tuning of a laser diode (LD) by the quantum-confined Stark effect. This is achieved by introducing tunneling barriers in the LD active region, as a result of which significant space-charge fields are generated during current injection, modulating the gain spectrum of the “lasing” quantum well. In such a “modified” InGaAs/AlGaAs LD, we observed up to 5-nm Stark-tuning of the lasing wavelength in the 900-nm spectral region. © 2003 American Institute of Physics.
