Paper Abstract

Recently, subcarrier multiplexing method combined with the conventional microwave techniques provides high capacity multichannel optical fiber communication. But as the microwave frequency gets higher, the carrier generation and carrier recovery circuits are more difficult to implement by using traditional microwave technology. This paper proposes a way to generate many subcarriers using only a single reference tone by deep phase modulation method. Tunabilities of operating band and carrier spacing are presented in experimental results. It is found that the optimum phase modulation index is 3.1 for minimum power deviation to generate 7 carriers. Those generated subcarriers can operate from dc to K-band that can be used in transmitting end or receiving end.
