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.

High-speed and robust modulation of arbitrary polarization states based on Sagnac interferometer for quantum key distribution

Zexu Wang, Huaxing Xu, Bo Liu +3 more

In polarization-encoding quantum key distribution (QKD) systems, achieving high-speed, robust, and low-error polarization modulation helps to increase the secure key rate (SKR). Moreover, the advanced QKD protocols place higher demands on the system’s photon preparation capability, which implies providing additional polarization states for practical implementation. Here, we redesign the Sagnac interferometer and utilize the non-reciprocity of the lithium niobate modulator to eliminate the reverse modulation that limits the modulation speed. The proposed scheme enables high-speed, robust, and low-error modulation with arbitrary polarization states. The average bit error rate (BER) for the 10 min measurement is 0.2332% with a system repetition frequency of 16.5 GHz.

Fabrication of high extinction ratio lithium niobate integrated optical modulators using photorefractive trimming

Aleksandr V. Shamrai, Aleksandr V. Tronev, Mikhail V. Parfenov +3 more

A method for increasing the extinction ratio of integrated optical Mach-Zehnder modulators based on LiNbO3 via the photorefractive effect is proposed. The influence of the photorefractive effect on the X- and Y-splitters of intensity modulators is experimentally studied. An increase in the modulator extinction ratio by 17 dB (from 30 to 47 dB) is obtained. It is shown that fabricated modulators with a high extinction ratio are important for quantum key distribution systems.

10 GHz robust polarization modulation towards high-speed satellite-based quantum communication

Ze-Xu Wang, Huaxing Xu, Ju Li +9 more

In practical satellite-based quantum key distribution (QKD) systems, the preparation and transmission of polarization-encoding photons suffer from complex environmental effects and high channel loss. Consequently, the hinge to enhancing the secure key rate (SKR) lies in achieving robust, low-error, and high-speed polarization modulation. Although the schemes that enable self-compensation demonstrate remarkable robustness, their modulation speed is limited to around 2 GHz to prevent the interaction between the electrical signal and the reverse optical pulses. Here, we utilize the non-reciprocity of the lithium niobate modulators and eliminate the modulation on the reverse optical pulses. This characteristic is widely available in the radio-frequency band, allowing the modulation speed to no longer be limited by the self-compensating optics and enabling further increases. The measured average intrinsic quantum bit error rate of the four polarization states at 10 GHz system repetition frequency is as low as 0.53% over 10 min without any compensation. The simulation results show that our scheme can maintain a SKR of about 5 kbps even at the extreme communication distances between the satellite and the earth. Our work can be efficiently applied in high-speed, high-loss satellite-based quantum communication scenarios.

A method for photorefractive trimming of lithium niobate integrated optical modulators was developed. An improvement in the extinction ratio in a Mach-Zehnder (MZ) modulator by photorefractive precision adjustment of its couplers was achieved. An increase in the extinction ratio by 18 dB (from 30 to 48 dB) was demonstrated.

High-speed robust polarization modulation for quantum key distribution

Yang Li, Yu-Huai Li, Hongbo Xie +7 more

Polarization modulation plays a key role in polarization-encoding quantum key distribution (QKD). Here, we report a new, to the best of our knowledge, polarization modulation scheme based on an inherently stable Sagnac interferometer. The presented scheme is free of polarization mode dispersion and calibration as well as insensitive to environmental influences. Successful experiments at a repetition frequency of 1.25 GHz have been conducted to demonstrate the feasibility and stability of the scheme. The measured average quantum bit-error rate of the four polarization states is as low as 0.27% for 80 consecutive minutes without any adjustment. This high-speed intrinsically stable polarization modulation can be widely applied to many polarization-encoding QKD systems, such as BB84, MDI, etc.
