A photonic broadband signal frequency conversion and bandwidth multiplication system is demonstrated based on a Fourier domain mode-locked optoelectronic oscillator (FDML-OEO). In this method, frequency conversion is achieved by using the selected optical sideband as the optical source of the FDML-OEO. An experiment is conducted, and a linear frequency modulation (LFM) signal with different central frequencies are converted. The central frequency of the converted signal can be tuned simply by adjusting the wavelength of the optical carrier. Due to the feature of low phase noise of the OEO, the degradation of the converted signal is almost neglected. Broadband signals with different time widths are also converted in terms of fibre length regulation. Furthermore, bandwidth multiplication of the LFM signal is achieved by selecting a second-order optical sideband as the optical source of the FDML-OEO.

基于傅里叶域锁模光电振荡器的光子宽带信号频率转换和带宽倍增

基于傅里叶域锁模光电振荡器 (FDML-OEO) 演示了光子宽带信号频率转换和带宽倍增系统。在该方法中,通过使用选定的光边带作为 FDML-OEO 的光源来实现频率转换。进行了实验,对不同中心频率的线性调频(LFM)信号进行了转换。可以通过调整光载波的波长来简单地调整转换信号的中心频率。由于OEO的低相位噪声特性,转换信号的劣化几乎可以忽略不计。不同时间宽度的宽带信号也在光纤长度调节方面进行了转换。此外,
