Recently, it is studied for a large scale operation in the quantum information processing using linear optical elements such as beam splitter (BS). Frequency-domain BS which is different from spatial-domain BS has been studied and demonstrated. In our research, we use two periodically poled lithium niobate (PPLN) as frequency-domain BS for constructing the Mach-Zehnder interferometer which is one of the most basic optics circuit and observed the interference between two different wavelengths.
