Paper Abstract

Theory and experiment at 1.3 μm are presented to describe and compare the behavior of two kinds of channel waveguide modulators in Ti-indiffused LiNb03: Mach-Zehnder interferometers and directional couplers. Each device can be operated as a linear modulator when biased to an appropriate point, either by passive geometrical means or by application of a DC voltage. However, the device voltage responses differ, being sinusoidal for an interferometer and varying as sin2x/x2 for a directional coupler. There is good agreement between calculated and measured device responses. The linear dynamic range of each kind of modulator is reported. We have measured linearity over 76 dB and voltage sensitivities of ~ 13 μV.
