Abstract

A novel modeling approach for Mach–Zehnder electro‐optic modulators (MZ–EOMs) in microwave optical systems is presented. MZ–EOM traveling‐wave electrodes are fully characterized by an electrode transfer function (ETF) which considers internal design parameters. This ETF is approximated by the modulator electrical response that, jointly with the half‐wave voltage at dc and the optical insertion loss, are the three parameters on which the model is based. Frequency‐ and time‐domain models are provided. An excellent agreement between theoretical and experimental results validates the proposed modeling approach, useful in simulating microwave optical systems. © 2001 John Wiley & Sons, Inc.

## Abstract A new optical receiver is proposed for optical time‐division multiplexing (OTDM) systems, which uses two cascaded LiNbO~3~ Mach–Zehnder intensity modulators as an ultrafast electrooptic (EO) time gate to demultiplex the OTDM data.

## Abstract A novel integrated Mach–Zehnder modulator fabricated on Z‐cut lithium niobate wafers is presented. The optical waveguides were fabricated by the Zn‐diffusion method, which allows monomode TM propagation at the wavelength of interests by choosing the channel waveguide width. The TM‐mode
