摘要：

We propose, analyze, and demonstrate a novel transmitter architecture for links that support transmission of baseband data and subcarrier multiplexed control channels. The architecture utilizes a differential external integrated-optic modulator to electrooptically combine the baseband and subcarrier multiplexed data onto an optical carrier. An analytical model is presented that allows optimization of the SNR of the received baseband and control data channels based on modulation parameters. This optimization is based on tradeoffs that result when the baseband and subcarrier channel are combined using a nonlinear modulator transfer function. We experimentally demonstrate a link based on this architecture with 2.5-Gb/s baseband and 100-Mb/s control data multiplexed on a 5.5-GHz subcarrier. Analytical and measured experimental results are compared and are shown to be in good agreement.
