Precise lightwave modulation for digital and analogue optical communications

Tetsuya Kawanishi

Abstract

This paper describes high-speed electro-optic device technologies for radio-on-fiber (RoF) systems. Digital and analog signals can be transmitted over a fiber, in RoF systems. Multi-level modulation plays important roles both in wired and wireless systems. Quadrature amplitude modulation signals can be synthesized by using parallel Mach-Zehnder modulators.
