In this paper, a three dimensional numerical modeling of an optically controlled nanoscale FinFET considering quantum mechanical effects has been theoretically examined and analyzed. The device characteristics are obtained from the self-consistent solution of 3D Poisson-Schrodinger equation using WKB (Wentzel Kramers Brilloin) interpolation-Wavelet method. This method provides more accurate results by dynamically adjusting the computational mesh and scales the CPU time linearly with the number of mesh points using oscillating interpolation derived from WKB asymptotics, hence reducing the numerical cost. The results obtained for dark and illuminated conditions are used to examine the performance of the device for its suitable use as a photodetector.
