Abstract

The intrinsic power dissipation of an absorption-based light modulator is simply the absorbed optical power. However, most of the total dissipation in electrically driven multiple quantum well (MQW) modulators operating with light incident normal to the device plane is nonintrinsic, resulting from motion of photogenerated carriers through externally applied electric fields.
