Abstract :
We investigate the modal properties, for TE polarization, of graded-index porous silicon slab waveguides with linearly varying dielectric permittivity. Using transfer matrix formalism, we derive all-analytical expressions, in terms of special functions of the Bessel class, for the propagation constant and the transverse profile of each mode.
