Abstract :
Summary form only given. A multiple quantum well InGaAsP-InP Mach-Zehnder (MZ) interferometer with a high-contrast ratio of >40 dB, and a low voltage-length product of 1.8 V-mm, is demonstrated and analyzed. Using the Lanczos-Helmhortz beam propagation method (LHBPM), we find that the linear and quadratic electrooptic coefficients for lnGaAsP quantum wells
