Abstract

By employing electro-optic Pockels effect of periodically poled lithium niobate, two optical signals with orthogonal linear polarization states can be switched between each other, which is a novel mechanism to demonstrate polarization-based binary all-optical logic functions, such as the basic controlled-NOT, AND and OR gates. By exploiting these basic gates with other XOR and XNOR gates realized in our previous experiment, complicated Boolean calculation should be expected.

Polarization-based all-optical logic controlled-NOT, XOR, and XNOR gates employing electro-optic effect in periodically poled lithium niobate

Yinxing Zhang, Yuping Chen, Xianfeng Chen

Based on electro-optic Pockels effect of periodically poled lithium niobate, different polarization-based binary all-optical logic functions: controlled-NOT, XOR, and XNOR gates were demonstrated by altering the linear polarization state of input optical signal about 90° on the polarization plant. Because the depletion of signal intensity in polarization-based logic gates is smaller than that of digital logic signal in intensity-based logic gates and almost negligible, this scheme has potential application in realizing complex logic functions by cascading several basic gates.

We propose AND, NOR, and XNOR logic gates realized simultaneously for 40-Gb/s networks, in which the realization of NOR and XNOR logic gates using only MgO-doped periodically poled lithium niobate (MgO: PPLN) is reported.In our configuration, we exploit broadband quasi-phase matching (QPM) cascaded second harmonic and difference-frequency generation (cSHG/DFG), cascaded sum-frequency and differencefrequency generation (cSFG/DFG) in one MgO:PPLN, and the narrow band QPM sum-frequency generation (SFG) in another MgO:PPLN.The performance, including the quality-factor (Q-factor) and extinction ratio (ER), of the proposed multifunctional logic device is also simulated.

All-optical flexible 20-Gb/s logic and gate based on cascaded sum- and difference-frequency generation in a periodically poled lithium niobate waveguide is proposed and experimentally demonstrated. The theoretical analyses further indicate that 40-, 80-, and 160-Gb/s ultrahigh-speed logic and operations can potentially be performed. Moreover, it is expected that the and output can be tuned in a wide wavelength range (67 nm) with slight fluctuation of the Q-factor and extinction ratio.

Invertible all-optical logic gate on chip

Zhan Li, Jia‐Yang Chen, Yong Meng Sua +3 more

We demonstrate an invertible all-optical gate on chip, with the roles of control and signal switchable by slightly adjusting their relative arrival time at the gate. It is based on the quantum Zeno blockade (QZB) driven by sum-frequency generation (SFG) in a periodically poled lithium niobate microring resonator. For two nearly identical nanosecond pulses, the later arriving pulse is modulated by the earlier arriving one, resulting in 2.4 and 3.9 power extinction between the two, respectively, when their peak powers are 1 mW and 2 mW, respectively. Our results, while to be improved and enriched, herald a new, to the best of our knowledge, paradigm of logical gates and circuits for exotic applications.
