High-speed nonreciprocal modulation in bidirectional links based on periodically poled lithium niobate modulator

Zexu Wang, Feifei Yin, Kun Xu +1 more

Non-reciprocal modulation in bidirectional links eliminates the modulation speed limitation caused by preventing electrical signals from simultaneously modulating light in both directions, thereby enabling the system to operate at higher speeds. Conventional lithium niobate modulators only support this functionality under specific conditions. The periodically poled lithium niobate (PPLN) based modulator we propose supports non-reciprocal modulation across expanded application scenarios. Simulation results demonstrate that the PPLN modulator achieves high-speed modulation for both continuous wave and pulsed light. A polarization encoder based on a Sagnac interferometer using the PPLN modulator enables random modulation of four polarization states at a system repetition frequency of 10GHz, with an average polarization extinction ratio exceeding 20dB.

Recent advances in poled lithium niobate

Lithium niobate is a versatile material for both classical and quantum photonics, recognized for its outstanding electro-optic and nonlinear optical properties. Through a process known as poling, periodic ferroelectric crystal domains can be engineered to enable quasi-phase-matched frequency conversion, efficient modulation, and the generation of quantum light sources. The emergence of lithium niobate on insulator technology has further enhanced its suitability for scalable integrated photonics, offering ultra-low optical losses and strong light confinement while retaining the material's inherent advantages. Here, the techniques used to fabricate and characterize periodically poled lithium niobate are reviewed. Key developments are discussed, offering insights into the future of domain engineering of lithium niobate.
