Detectors for high energy physics experiments have become extremely large in recent years and their size is still growing. This imposes new problems on readout electronics. A Mach-Zehnder type optomodulator has been investigated for the last quarter of a century, but its application for analog signal transmission in a physics experiment is a quite new idea. Recent studies have proven that Mach-Zehnder type optomodulators have a good potential in such applications. It will enable more than an order of magnitude reduction of cable volume and will be free from noise pickup and cross talk. Almost no attenuation through a long signal path in light fibers is also an asset when a detector size is very large. Power consumption is also minimal. 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 low enough temperature coefficient so that it could be used for some physics experiments. A light wavelength of 1.55 micron was chosen for the unit.
