Phase regeneration of phase-shift keying signals is theoretically proposed, we believe for the first time, based on the efficient optical parametric amplification (OPA) process in a highly nonlinear symmetric hybrid plasmonic waveguide. This optimized stacked waveguide with nonlinear organic materials has a relatively low loss of about 0.005 dB/μm and an effective nonlinear OPA coupling coefficient up to 60 ps/m/W(1/2). The phase-recovery process was achieved in this waveguide within a length as short as 150 μm.
本文从理论上提出了基于高效光参量放大(OPA)过程在高度非线性对称混合等离子体波导中实现相移键控信号的相位再生,我们相信这在该领域尚属首次。该优化的堆叠波导采用具有较低损耗(约 0.005 dB/μm)和有效非线性 OPA 耦合系数高达 60 ps/m/W(1/2)的非线性有机材料。在该波导中,仅需 150 μm 的短长度即可实现相位恢复过程。
