  1. The simulated results show that we can improve the sensitivity by setting the optical bias at / 2, reducing the gap of electrode, increasing the overlap integral factor, reducing the insert lose, adopting suitable segmentation number, increasing the electrode length, increasing the optical power, reducing the wavelength and the relative intensity noise and reducing the receive bandwidth ; obtain the wider bandwidth utilizing reducing the electrode length and the capacitance of modulator, segmentation the electrode ; increase the dynamic range using lowering noise, increasing the optical power at the detector and lower optical bias

    通過計算得知,使傳感器相位偏置為/ 2 ,減小電間距,提高電光重疊因子,減小器件插入損耗,採用合適的分段數,增加電度,增大光功率,降低激光的,減小相對強度噪聲,減小接收帶寬,對提高靈敏度的效果是非常明顯的。而減小度,降低調制器電容,電分段,都可以獲取較大的帶寬。降低系統噪聲;增加到達探測器的光功率,採用較低的光學偏置,都可以增大性動態范圍。
