“…Optical constants, such as n and a, for CdS x Se 1Àx in the limited composition ranges have also been reported [320][321][322]. The n(E) dispersion in Mg x Zn 1Àx S y Se 1Ày /GaAs has been measured by several authors [323][324][325]. These data showed that the smaller E 0 -gap material has a larger n value, as in many tetrahedral semiconductor alloys.…”

“…The configuration that has been proposed here comprises ZnSe prism (n=2.457) and 0.9 μm thick liquid crystal layer of E44 (4-pentyl-4-ceyanobiphenyl) as dielectric layer which has been crushed between two silver layers (n=0.469+9.320i) having the thicknesses of 50 nm and 200 nm respectively at a free space wavelength of 1550 nm at 25 0 C [14][15][16]. The proposed configuration as shown in Fig.…”

First time a theoretical approach towards the enhancement of spatial and angular Goos-Hanchen (GH) shift and Imbert-Fedorov (IF) shift for a Gaussian beam and Laguerre-Gaussian beam are observed, designed and simulated in four layer Kretschmann-Raether geometry at a free space wavelength of 1550 nm. Here the proposed configuration comprises a ZnSe prism and a liquid crystal layer of E44 between two silver layers through which spatial and angular GH shift and IF shift can be observed for Gaussian beam as well as LaguerreGaussian beam whereas the exact output beam position can only be accurately identified with the composite effect of spatial and angular GH shift and IF shift. Here with the variation of incident angle from 40 0 to 50 0 , the spatial and angular GH shift and IF shift have been calculated for two types of beams. This idea expedites the concept of optical tuning at μm ranges and reveals the exact output beam position for every experiments with different beams.

“…In our proposed scheme, a liquid crystal layer (as dielectric layer) of polymide (n=1.78, d 3 =4.5m) [3] is sandwiched between two metal layers of silver (n = 0.234+7.214i) having thickness of 50 nm and 200 nm respectively at a wavelength of 1064 nm and 25 0 C temperature [4,5]. Here fundamental radiation comes from a continuous mode locked Nd:YAG laser, lasing at 1064 nm with an acousto-optic Q-switch yielding a pulse train of 25×100 picosecond pulses at a rate of 500 Hz.…”

This paper first time observed, designed and simulated the surface plasmon enhanced tunable Goos-Hänchen shift with varying refractive index of the dielectric layer in Kretschmann-Reather geometry formed by a ZeSe prism,50 nm silver layer, 4.5 m liquid crystal layer (as dielectric layer) and 200 nm thin silver layer. Here the Goos-Hänchen shift is tuned from (10-72) nm with the change in refractive index of the liquid crystal layer with varying applied voltage.
