The energy structure and the value of the electrooptic effect in heteroepitaxial structures (HES) with multiple InGaAlAs / InAlAs quantum wells have been studied. The interferometric method has been developed to determine small changes in the refractive index under transverse transmission of light through a layered structure. The length of the Mach-Zehnder interferometer for the modulator at HES with multiple InGaAlAs / InAlAs quantum wells has been chosen.

Two Stages

A new approach to Fano resonance of excitons in quantum-confined systems is presented based on the 4×4 Luttinger Hamiltonian. This method, consisting of two stages, namely, the adiabatic expansion and the R-matrix propagation, allows to implement high-resolution calculations of Fano profiles having natural spectral widths without any empirical broadening parameter which is indispensable in conventional methods. As a demonstration, this approach is applied to Fano resonance of an exciton in a wide quantum well, where hole-subband mixing is substantial and a complicated energy-structure is expected. Resulting spectral profiles show rich fine structures due to overlap with adjacent resonances and the hole-subband mixing.
