Special Issue Information

Dear Colleagues,

Designing photonic circuits and devices has become a current research hotspot due to the rapid advancement of science and technology. With high speed, low loss, high integration and other benefits, photonic devices leverage the properties of light to realize a variety of functions, including photoelectric conversion, optical communication and optical computing. One of the essential technologies for photonic device function is circuit design. Reasonable circuit design allows for photonic devices to operate more efficiently. This Special Issue aims to present research findings and practical applications in relevant fields, while delving deeply into the most recent developments and anticipated trends in photonic device and circuit design.

This Special Issue's research topics encompass, but are not limited to, the following:

  • Research and application of photonic devices;
  • Application of circuit design to photonic devices;
  • Optimization and integration of photonic devices and circuit design;
  • Applications of photonic devices and circuit design in communications, computing and other fields;
  • Future trend and research prospect.

In the context of the rapid development of modern science and technology, time synchronization technology has become a critical support in the fields of communication and scientific research. Especially in large-scale research projects such as the China Spallation Neutron Source, the accuracy of time synchronization directly affects the precision of experimental data and the reliability of experimental results. White Rabbit (WR) technology surpasses the sub-microsecond precision limitations of traditional PTPs by precisely controlling and calibrating the delays between master and slave clocks, achieving sub-nanosecond time synchronization that meets the stringent timing accuracy requirements of 5G networks and quantum communications. To meet the demands for high precision, high flexibility, and broad applicability, a switch with WR functionality has been designed based on the Zynq platform. This design not only reduces the number of required components and the complexity of the soldering process but also allows for simple AXI bus communication between the PS and PL ends, thereby decreasing the development time and cost of both software and hardware. The hardware design includes power circuits, clock circuits, and SFP interface circuits. The time synchronization module encompasses the design of the RTU, NIC, SoftPLL, and PPS modules, as well as the design of the AXI to Wishbone bridge. Testing has shown that this switch can achieve sub-nanosecond level time synchronization accuracy. Full article

The pulse laser emission circuit plays a crucial role as the emission unit of time-of-flight (TOF) LiDAR. This paper proposes a nanosecond-level pulse laser diode array drive circuit for LiDAR, primarily aimed at addressing the issue of high-speed scanning drive for the laser diode array at the emission end of solid-state LiDAR. Based on the single pulse laser diode drive circuit, this paper innovatively designs a circuit that includes modules such as a boost circuit, linear power supply, high-speed gate driver, GaN field-effect transistor, and pulse narrowing circuit, realizing an 8-channel laser diode array drive circuit. This circuit can achieve a pulse laser array drive with a single channel operating frequency of greater than 100 kHz, an output pulse width of less than 5 ns, a peak power greater than 75 W, and a channel switching time that does not exceed 1 μs. A field programmable gate array (FPGA) is used to control the operation of this circuit and perform a series of performance tests. Experimental results show that this circuit has a high repetition rate, large output power, a narrow pulse width, and fast switching speeds, making it highly suitable for use in the optical emission module of solid-state LiDAR.
