The regime of strong light matter coupling is reached, when the characteristic energy of the interaction between light and material excitations exceeds all characteristic broadenings in the system. It can be realized in planar microcavities, where confined photonic mode resonantly interacts with an exciton, formed in a 2D active layer placed in its antinode. In this case, novel type of hybrid half light- half matter elementary excitations, known as exciton polaritons are formed.

In our talk we will consider theoretically the properties of the polaritons in the systems based on regular arrays of carbon nanotubes or organic materials. Our focus will be on the possibility to reach the regime of exciton brightening and analysis of the microscopic mechanisms of nonlinear optical response in these systems.
