Abstract

Integrated silicon-based MZ optical modulators are used in a variety of optical-network domains. Applications in various modulation formats at 100 Gb/s and beyond are classified with respect to the transmission distance, and the usage of silicon-based optical modulators is discussed in this chapter. Then, the transmission characteristics of silicon-based optical modulators are reviewed in terms of modulation formats such as NRZ-OOK and PAMn in intensity modulation; BPSK, QPSK, DP-QPSK, and PDM nQAM in phase modulation; and DMT in sub-carrier modulation. Characterization of transmission performances is essential to evaluate optical modulators for a given application. The apparatus for transmission characterization of siliconbased optical modulators and their characteristics is described with respect to the modulation formats. This part can be used as a reference document to conduct transmission measurement of modulators. With the transmission characteristics described there, the reader can verify that integrated siliconbased optical modulators are suitable to a wide range of applications in highcapacity optical networks.
