Abstract

A novel, triangular microwave waveform generating technique using a polarization-multiplex optoelectronic oscillator (OEO) is proposed. The proposed method uses fundamental ( $f_{r f}$ ) and triple frequency tone ( $f_{r f}^{'} = 3 f_{r f}$ ) signals to drive two sub-MZMs. Thus, carrier suppression modulation along two orthogonal polarization orientations is possible. Due to harmonic injection coupling, the two OEO oscillations can be precisely adjusted at 1:3. Due to tone polarization orthogonality, photo-detection yields no cross-beating terms. While adjusting the D.C. biases and modulation indices of the two sub-MZMs, the harmonic power ratio is suitably adjusted to create triangular microwave waveforms. The suggested OEO loop techniques avoid optical filters. Proof of concept experiments show that the proposed approach generates frequency-doubled triangle microwave waveforms with full-duty cycles.

使用DP-MZM产生全占空比倍频三角形微波波形

提出了一种利用偏振多路光电振荡器（OEO）产生三角形微波波形的新技术。所提出的方法使用基频（fr f ${f}_{rf}$）和三频音调(F r F ' = 3f rf ${f}_{rf}^{^{\素数}}=3{f}_{rf}$)信号驱动两个子mzm。因此，沿两个正交偏振方向的载波抑制调制是可能的。由于谐波注入耦合，两个OEO振荡可以精确地调整为1:3。由于色调偏振正交性，光探测不会产生交叉跳动项。在调整直流偏置和调制指数的同时，适当调整谐波功率比，形成三角形微波波形。建议的OEO环路技术避免了光学滤波器。概念验证实验表明，该方法可产生全占空比的倍频三角形微波波形。
