Using quantum hydrodynamic model, quantum effects (via Bohm potential) on modulational amplification characteristics of semiconductor magneto-plasmas are investigated. Expressions are obtained for the threshold pump amplitude and the growth rate of modulated beam with including and excluding quantum effects. Numerical analysis is performed for n-InSb/CO₂ laser system. The dependence of the threshold pump amplitude and the growth rate of modulated beam on wave number, applied magnetic field, and plasma carrier concentration are explored. The lowering in threshold pump amplitude and enhancement of growth rate of modulated beam are observed by incorporating the quantum effects. The analysis provides detailed information of quantum effects on semiconductor magneto-plasmas and establishes the technological potentiality of semiconductor magneto-plasmas as the hosts for fabrication of efficient optical modulators.
