Abstract An energy efficient and all optical 24 tupled radio frequency multiplication is proposed to generate 60 GHz using two cascaded dual parallel polarization modulators (DPPolMs). Detailed theoretical analysis is carried out using Jones matrix formalism. ±12th order optical sidebands are obtained at the output of second DPPolM which beat at the photo-detector (PD) to produce frequency 24 tupled RF carrier. A good optical spurious suppression ratio (OSSR) of 34.4 dB is obtained for ±12th order optical sidebands and radio frequency spurious suppression ratio (RFSSR) of 25.8 dB is obtained for 24-tupled RF signal. We verify the accuracy of the analysis with simulations in OptiSystem and a close match between theory and simulation results are obtained. We showed a scheme to generate four subcarrier signals in 57–64 GHz license free band using subcarrier multiplexing with an additional polarization modulator placed after cascaded DPPolMs. 10 km single mode fiber transmission performance of the optical sidebands in 57–64 GHz sub-band shows negligible power penalty of 0.3 dB at BER 10 - 9 .

使用级联双平行偏振调制器生成具有 24 元倍频的光子 60 GHz 子带

摘要 提出了一种节能的全光 24 元射频倍增，以使用两个级联双平行偏振调制器 (DPPolM) 产生 60 GHz。详细的理论分析是使用琼斯矩阵形式进行的。在第二个 DPPolM 的输出处获得 ±12 阶光学边带，其在光电检测器 (PD) 处跳动以产生频率为 24 元组的 RF 载波。对于±12 阶光边带，可获得34.4 dB 的良好光杂散抑制比(OSSR)，对于24 元RF 信号可获得25.8 dB 的射频杂散抑制比(RFSSR)。我们通过 OptiSystem 中的模拟验证了分析的准确性，并获得了理论与模拟结果之间的密切匹配。我们展示了一种在 57-64 GHz 免许可频段中生成四个子载波信号的方案，该方案使用子载波复用和放置在级联 DPPolM 之后的附加偏振调制器。57–64 GHz 子带中光边带的 10 km 单模光纤传输性能显示，在 BER 10-9 下 0.3 dB 的功率损失可以忽略不计。
