Paper Abstract

We perform structural optimization of negative prechirping Franz-Keldydh InGaAsP bulk electroabsorption (EA) modulator in terms of transmission change and waveguide length. For the optimization, we calculate the chirp parameter ((alpha) c) of EA modulator from the slope of n versus k curve. In the optimization process, for a given (alpha) c and modulation voltage change we calculate contrast ratio, propagation loss, optimal waveguide length, optimal transmission change varying intrinsic region thickness and bandgap wavelength. Detailed results on optimized structures are presented.
