Abstract
We have constructed a vertical-cavity, surface-emitting laser with a v oltage-controlled quantum well absorber in the upper mirror stack. If the lasing wavelength of this device is designed to be slightly longer than the absorber band edge, sharp negative differential resistance c an be obtained in the absorber under lasing conditions. We present str ong experimental evidence that this behavior arises from redshifting o f the absorption excitonic peak due to the quantum confined Stark effe ct. Design criteria are proposed for applications including high speed modulation and self-pulsation. (C) 1998 American Institute of Physics . [S0003-6951(98)03339-7].
