Journal ArticleDOI
Five-port optical router for photonic networks-on-chip
Ruiqiang Ji,Lin Yang,Lei Zhang,Yonghui Tian,Jianfeng Ding,Hongtao Chen,Yangyang Lu,Ping Zhou,Weiwei Zhu +8 more
TL;DR: A spatially non-blocking five-port optical router, which is based on microring resonators tuned through the thermo-optic effect, is experimentally demonstrated and the routing functionality of the optical router is verified.
Journal ArticleDOI
Demonstration of directed XOR/XNOR logic gates using two cascaded microring resonators
Lei Zhang,Ruiqiang Ji,Lianxi Jia,Lin Yang,Ping Zhou,Yonghui Tian,Ping Chen,Yangyang Lu,Zhenyu Jiang,Yuliang Liu,Qing Fang,Mingbin Yu +11 more
TL;DR: Numerical simulation results indicate that the length difference between the upper waveguide and the under waveguide can change the output spectrum characteristics of the device, which acts like a Mach-Zehnder interferometer (MZI).
Journal ArticleDOI
Four-channel reconfigurable optical add-drop multiplexer based on photonic wire waveguide
TL;DR: A four-channel reconfigurable optical add-drop multiplexer based on silicon photonic wire waveguide controlled through thermo-optic effect firstly reported in this paper is designed and fabricated.
Journal ArticleDOI
Proof of concept of directed OR/NOR and AND/NAND logic circuit consisting of two parallel microring resonators
Yonghui Tian,Lei Zhang,Ruiqiang Ji,Lin Yang,Ping Zhou,Hongtao Chen,Jianfeng Ding,Weiwei Zhu,Yangyang Lu,Lianxi Jia,Qing Fang,Mingbin Yu +11 more
TL;DR: A directed OR/NOR and AND/NAND logic circuit consisting of two parallel microring resonators using two electrical signals representing the two operands of the logical operation to modulate the two MRRs through the thermo-optic effect, respectively is proposed and demonstrated.
Journal ArticleDOI
Microring-resonator-based four-port optical router for photonic networks-on-chip
Ruiqiang Ji,Lin Yang,Lei Zhang,Yonghui Tian,Jianfeng Ding,Hongtao Chen,Yangyang Lu,Ping Zhou,Weiwei Zhu +8 more
