Nonlinear intersubband terahertz absorption in asymmetric quantum well structures

Intersubband and Interband Absorptions in Near-Surface Quantum Wells Under Intense Laser Field

“…, for an optical transition between two subbands can be calculated by using the compact density matrix method (Bedoya & Camacho, 2005;Rosencher & Bois, 1991) and a typical iterative procedure (Ahn & Chuang, 1987). The linear and nonlinear absorption coefficients are written (Unlu et al, 2006;Ozturk, 2010) as: …”

Intensity-dependent nonlinear optical properties in a modulation-doped single quantum well

“…Yuh and Wang [30] investigated the field-dependent optical properties of a step QW structure. The THz nonlinear absorption of asymmetric double quantum wells is calculated by Bedoya and Camacho [31]. Karabulut et al [32][33][34] investigated the linear and nonlinear optical properties for QW structures having different confining potential profiles.…”

“…Many studies associated with both the ISB optical transitions and the nonlinear optical properties induced by interband and ISB transitions in semiconductor quantum well [28][29][30][31][32][33][34][35][36][37][38][39] and quantum dot (QD) [40][41][42] structures are reported in the literature. Ahn and Chuang [28] calculated the linear and nonlinear ISB optical absorption coefficients in a semiconductor QW.…”

The effect of hydrostatic pressure on subband structure and optical transitions in modulation-doped quantum well

“…There are many studies associated with the intersubband optical transitions in semiconductor QW [8][9][10][11][12][13][14][15][16][17][18][19]. Ahn and Chuang [8,9] have calculated the effect of the electric field on the intersubband optical absorption in a quantum well.…”
