Paper Abstract

We review the photo-driven directed charge, spin and acoustic phonon transport in dielectrics and semiconductors, in bulk and hetero-structures, lacking spatial inversion symmetry. We express these photo-galvanic effects in terms of photo-induced driving forces bilinear in the coherent light field amplitude mediated through the spatial asymmetry of the medium. We discuss their interrelations with nonlinear optical analogues and also nonlinear optical time resolved techniques for their study. These issues are of certain relevance in optoelectronics and photonics and in the emerging fields of phononics and photo-spintronics as they introduce new unidirectional and nonreciprocal photonic functionalities. They are manifestations of photo-driven ratchet and pawl processes.
