| Abstract: | An integrated microwave photonic phase shifter based on vector-sum technique in silicon on insulator was verified and designed. The principle of phase-shift was demonstrated and the components were designed in detail. The interference was taken into account in the design and 0.3 nm line-width of a light source was required to make the coherent interference smallest even to be neglected. Owing to the compact size and excellent characteristics of integration, the proposed component has a promising utilization in optical communication and optical phased-array radar. |
