Abstract

Highlights: GH shift is controlled and modified under the effects of Kerr nonlinearity, Doppler broadening and Compton scattering. Maximum GH-shift in the reflection/transmission is investigated to ±3 λ . Above, the ϕ c = π / 6 GH-shift is saturated at λ in the reflection. GH-shift is the function of control fields, Kerr nonlinearity, Doppler broadening. Gh-Shift changes with incident and Compton scattered angles. The results have applications in nano-optics, trapping of optical data, micro-optics. Abstract: Reflection, transmission as well as absorption coefficients and the corresponding Goos Hänchen shift in reflection and transmission is controlled and modified under the effects of Kerr nonlinearity, Doppler broadening as well as Compton scattering. The summation of the absolute values of these coefficients gives a unit value in the presence of all these effects. Modification of the coefficients follows the normalization condition. Maximum GH-shift in the reflection/transmission is investigated to ± 3 λ . Above ϕ c = π / 6, the GH-shift is saturated at the value λ in both reflection/transmission. The positive as well as negative GH-shift is measured in the absence and presence of Compton scattered reflected/transmitted beam. The GH-shift is the function of control fields, Kerr nonlinearity, incoherent effect of Doppler broadening and incident as well as the Compton scattered angles. The results show potential applications in nano-optics, trapping of optical data, micro-optics, acoustics, sensor technology and plasma physics.
