We have proposed a new model for the calculation of excitonic electroabsorption based on modified previously reported models for bulk structure. The excitonic absorption spectra in high purity GaAs have been theoretically studied in the presence of e

The absorption spectrum in high-purity GaAs has been theoretically studied in the presence of electric field taking into account of excitonic transition and continuum band transition at room temperature. We have calculated the Stark shift, height of

We have compared and analyzed the theoretical possibility for the extreme reduction in the linewidth enhancement (α- factor) in strained layer quantum-well (QW) lasers for AlGaInAs and InGaAsP material. Valence band structure and optical gain in bot

Highly efficient surface normal spatial light modulators (SLMs) using ultrahigh purity GaAs layers (30 μm thick) grown on (100) — oriented n+ — GaAs substrate by liquid phase epitaxy (LPE) method have been realized. The extinction ratio of 25 dB
