The parametic resonence of confined acoustic phonons and optical phonons in quantum wells

The parametric resonance of confined acoustic and confined optical phonons in quantum wells by using a set of quantum kinetic equations for phonons is studied. The analytical expression of the tfueshold amplitude E6 of the field in quantum wells is obtained. The dependence of it on the temperature T of the s;ystem and the frequecy O of the external electromagnetic field is sfudied. Numerical compuLtations and graphs are performed for GaAs-GaAsAl quantum well. The results are compared wilh the case of unconfined phonons
