Abstract

In the present study, the effect of the depth of the confinement potential on the nonlinear optical of a GaAs quantum well with short-range bottomless exponential potential is studied in detail. The energy eigenvalues and eigenfunctions of this structure are calculated within the framework of effective mass and envelope function approximations. Analytic formulas for the linear, third-order nonlinear and total absorption coefficients and relative refractive index changes are obtained using the compact-density matrix approach (CDMA) and iterative method. Based on this model, our obtained numerical results are reported as a function of incident photon energy for several values of the depth of the confinement potential. The results show that the linear, third order nonlinear, and total absorption coefficients and relative refractive index changes are strongly affected by the depth of the confinement potential.

Özet

Sunulan bu çalışmada, kısa erimli dipsiz üstel potansiyelli bir GaAs kuantum kuyusunun doğrusal olmayan optiksel özellikleri üzerine kuşatma potansiyelinin derinliğinin etkisi ayrıntılı olarak çalışılmıştır. Bu yapının enerji özdeğer ve özfonksiyonları etkin kütle ve zarf fonksiyonu yaklaşımı çerçevesinde hesaplanmıştır. Doğrusal, üçüncü dereceden doğrusal olmayan ve toplam soğurma katsayısı ve bağıl kırılma indisindeki değimleri için analitik formüller kompakt yoğunluklu matris yaklaşımı (CDMA) ve yineleme yöntemi kullanarak elde edilmiştir. Bu modele dayanarak, elde ettiğimiz sayısal sonuçları kuşatma potansiyelinin derinliğinin birkaç değeri için gelen foton enerjisinin bir fonksiyonu olarak rapor ettik. Sonuçlar doğrusal, üçüncü dereceden doğrusal olmayan ve toplam soğurma katsayılarının ve bağıl kırılma indisi değişimlerinin kuşatma potansiyelinin derinliğinden kuvvetli bir şekilde etkilendiğini göstermiştir.
