| Abstrakt: | Develops a grating coupled infrared modulator at normal incidence based on intersubband transitions in gallium arsenide/aluminum gallium arsenide quantum wells. Provision of coupling by a diffraction grating; Behavior of modulation in nondiffracted order transmitted by modulator; Dependence of modulation length on transition wavelength; Calculation of near field diffraction. |
