Optical rectification coefficient of a two-dimensional quantum pseudodot system

Optical rectification coefficient associated with intersubband transitions in a two-dimensional quantum pseudodot system, under the influence of an uniform magnetic field is theoretically investigated. In this regard, the compact-density matrix approach and an iterative method are used to find the optical rectification coefficient of the pseudodot system. We have investigated the effects of an external magnetic field, the geometrical size and the chemical potential of the pseudodot system on this coefficient. It is found that optical rectification coefficient is affected by the external magnetic field, the geometrical size and the chemical potential of the pseudodot system.

► Magnetic field effect on the ORC of a 2DQPD system is theoretically investigated.
► Magnitude of the ORC is decreased with increasing the magnetic field strength.
► ORC is strongly size dependent and exhibits a red-shift with increasing the size.
► Magnitude of ORC decreases and its peak exhibits a blue-shift, as V0 is increased.
