The highly sensitive InP-based phase modulators based on stepped quantum wells are discussed. Optical absorption coefficient and change of index of the modulators are measured using the optical transmission, modulator's photoresponse and Fabry-Perot oscillation shifts. It is found that solid lines are also calculated. The results show that the change of index of the square quantum wells for absorption coefficient below 1 cm-1 is about ∼1×10-4/V.
