  We address the electromagnetic properties of two-dimensional electron gas
confined by a dielectric environment in the presence of both Rashba and
Dresselhaus spin-orbit interactions. It is demonstrated that off-diagonal
components of the conductivity tensor resulting from a delicate interplay
between Rashba and Dresselhaus couplings lead to the hybridization of
transverse electric and transverse magnetic surface electromagnetic modes
localized at the interface. We show that the characteristics of these hybrid
surface waves can be controlled by additional intense external off-resonant
coherent pumping.
