Electro-optical switches

B.J. Li,     Sun Yat-Sen University, China


This chapter introduces the developments of electro-optical switches and mainly focuses on Si-based semiconductor materials because of the very mature fabrication technology. The chapter first discusses theory and principles of single-mode, multi-mode interference, and plasma dispersion effect, followed by materials and fabrication of electro-optical switches. The chapter then discusses eight kinds of electro-optical switches. Finally, a brief discussion on the performance and challenges of electro-optical switches is given.
