iajs-987	Mohammad, AR. A. S.; Jabbar, A.	Modulation Function Calculation For Optical Semiconductor Fractal Modulator	2017	11	.pdf	application/pdf	1723	67	60	Abstract The research includes the study and calculation of the modulation function of Optical Semiconductor Fractal Modulator and spatial frequency for different values of Silicon modulator transmittance percentage(10%,35%,45%,58%),it found the relation between the modulation function of Silicon and spatial frequency, the exponential relation of all values of the transmittance , the best state of modulation function when the value of transmittance is T=58% ,also the research includes the study of the relation of transmittance with different values of refractive index of Silicon . N sequence number, R is radius of the modulator and S is spatial frequency (as shown in data tables 1, 2, 3 & 4), and by using the following relation :-[ 5] M i= ( Ii max – Iimin) ∕ (I imax + Iimin ) ………….(5)	cache/iajs-987.pdf	txt/iajs-987.txt
