We demonstrate a novel differential phase-shift-keying (DPSK) demodulator based on coherent perfect absorption (CPA). Our DPSK demodulator chip device, which incorporates a silicon ring resonator, two bus waveguide inputs, and monolithically integrated detectors, operates passively at a bit rate of 10 Gbps at telecommunication wavelengths, and fits within a mm-scale footprint. Critical coupling is used to achieve efficient CPA by tuning the gap between the ring and bus waveguides. The device has a vertical eye opening of 12.47 mV and a quality factor exceeding . The fundamental principle behind this photonic circuit can be extended to other formats of integrated demodulators.

硅光子中相干完美吸收的差分相移键控解调
我们演示了一种基于相干完美吸收(CPA)的新型差分相移键控(DPSK)解调器。我们的DPSK解调器芯片设备集成了硅环形谐振器,两个总线波导输入和单片集成检测器,可在电信波长下以10 Gbps的比特率无源运行,并且占用的空间仅为毫米级。临界耦合用于通过调整环形和总线波导之间的间隙来实现有效的CPA。该设备的垂直眼图张开率为12.47 mV,品质因数超过。该光子电路的基本原理可以扩展到集成解调器的其他格式。
