Bu çalışmada, ayarlanmış GaAs / GaAlAs çift kuantum kuyusunda kuşatılan
bir elektronun ilk üç bağlı düzeyi arasındaki geçişler için doğrusal, 3.
mertebeden doğrusal olmayan ve toplam soğurma katsayıları üzerinde elektrik
alan ve yapı-ayar parametresinin etkileri incelendi. Elde edilen sonuçlar,
soğurma spektrumunun yapı -ayar parametresine ve elektrik alan şiddetine
duyarlı olduğunu göstermektedir. Elektrik alan şiddeti ve yapı parametresi değiştirilerek,
soğurma spektrumunun amaca göre, maviye veya kırmızıya kayması ayarlanabilir ve
bu sonuçlar ayarlanmış çift kuantum kuyusunun optik özelliklerini ayarlamak ve
kontrol etmek için kullanılabilir.

Optical Properties of Tuned Double Quantum Well Under the Electric Field

Öz

In this study, the effects of the electric field
and structure-tune parameter on the linear, third order nonlinear and total
absorption coefficients for transitions between the first three bound states of
an electron confined within the tuned GaAs/ GaAlAs double quantum well are
investigated. The obtained results show that the absorption spectra is
susceptible to the structure parameter and the electric field. By changing the
structure parameter and intensity of the electric field, it can be adjusted a
blue or red shift in the absorption spectra according to purpose and these
results can be used to tune and control the optical properties of tuned double
quantum well.
