Abstract

Polarization sensitivity of InGaAsP electroabsorption (EA) modulators is analyzed by the fractional-dimensional approach. Chirping parameter alpha isthen calculated using Kramers-Kronig relations. It is found that polarization-insensitive and negative chirp operation can be realized simultaneouslyfor InGaAsP multiple-quantum-wells (MQW) EA modulators with optimized wellwidth and amount of strain. We propose a polarization-insensitive InGaAsP EA modulator with 9-nm-wide 0.38% tensile strained quantum wells. The chirping parameter alpha is estimated to be around -2 for the first 3 dB of transmission, while the modulation characteristics remain polarization-independent up to SO kV/cm, corresponding to an extinction ratio of over 15 dB.
