REFLECTION AND ABSORPTION-SPECTRA FROM MICROCAVITIES WITH RESONANT BRAGG QUANTUM-WELLS

We have studied theoretically the optical properties of microcavities with multiple quantum wells in the central layer. The calculations hav e been performed both numerically, on the basis of the transfer-matrix method, and analytically, in the classical electrodynamic approach. S pecial attention has been paid to resonant Bragg multiple quantum well s sandwiched between nonresonant distributed Bragg reflectors. In this case the Rabi splitting of the exciton-polariton branches has been sh own to increase in proportion to the square root of the well number. W e have generalized the theory to calculate oblique-incidence reflectio n and absorption spectra in microcavities and to describe angle-depend ent anticrossing between the photon and the exciton resonances. The fi ne structure of exciton-polaritons has been analyzed in particular cas es for both s- and p-polarized modes. (C) 1996 Optical Society of Amer ica.
