A low temperature coefficient optomodulator for analog signals transmission

Recent studies have proven that Mach-Zehnder type optomodulators have a good potential for analog signal transmission. If it does not have too large a temperature coefficient, it could be an excellent device for future experiments. The authors have studied its temperature coefficient and developed a unit that has a low enough temperature coefficient so that it could be used for some physics experiments. A light wavelength of 1.55 mu m is chosen for the unit. >
