Gorbatsevich et al. and Kibis suggested that a number of interesting galvano-magnetic effects could be observed in quantum structures where the symmetry with respect to the space coordinates inversion and time-reversal are broken simultaneously. In the paper of Kibis for example, the infinite triangular quantum well in an external magnetic field was considered and the anisotropy of electron momentum transfer due to interaction with phonons was predicted. The role of magnetic field was to provide the time-invariance breaking. In this work we considered the effect of anisotropy of electron momentum transfer due to interaction with polarized light using more realistic model of finite triangular quantum well. This anisotropy leads to the anisotropy of the real part of photoconductivity and as it follows from our calculations, the effect though not very great, could be measurable for the attainable values of magnetic field B≈5 T and the widths of quantum well.
