Abstract

A commercially available broadband (20 GHz) Titanium indiffused Lithium Niobate traveling wave Mach-Zehnder interferometer was evaluated for its wavelength sensitivity. The electrooptic transfer characteristic was measured over the wavelength range between 1500 nm and 1565 nm. Variations of the extinction ratio, intrinsic phase bias and the halfwave voltage were evaluated. Measurements confirmed that the halfwave voltage increases linearly with wavelength and the intrinsic phase bias varies inversely as predicted by theoretical analysis. The extinction ratio was found to remain approximately constant.
