2025 4th Conference on Semiconductor Photonics, Laser Manufacturing, and Silicon Photonics
Xin Wei
（ Professor of Institute of Semiconductors, Chinese Academy of Sciences）
Abstract of the Speech：Photonic Crystal Surface-Emitting Lasers (PCSELs) exhibit high output power and high beam quality over large-area cavities. However, as the size of the photonic crystal (PhC) cavity increases, the PhC band mode spacing decreases, making single-mode operation challenging. We propose a design method that utilizes accidental Dirac cones and tunes the range of the flat band to address the scaling challenges in size and power. By incorporating symmetry breaking, a finite quality factor at the Γ point and a large Q-factor contrast are observed. We further analyze the relationship between the range of flat bands and the structural parameters of the PhC. We believe that this approach offers a promising pathway for achieving robust single-mode operation in large-area PCSELs.

（ CTO of Nantong Tri Optic Integrated Optoelectronic Technology Co., Ltd.）
Abstract of Speech：Driven by the rapid advancement of artificial intelligence (AI) and continuous innovation in the optoelectronics industry, photonic chips based on InAs/GaAs quantum dot (QD) materials—particularly QD lasers, amplifiers, and superluminescent diodes—have demonstrated significant potential across multiple high-end application fields. These include optical interconnects for data communication and intelligent computing, light sources for automotive fiber-optic communications, as well as single-photon sources and ultrafast lasers for quantum technologies. Thanks to advantages such as low threshold current density, high-temperature stability, narrow linewidth, long lifespan, and high resistance to optical feedback, quantum dot lasers are poised to become core enabling devices for next-generation optical communication and optical computing. Especially in the field of silicon photonic integration, QD lasers' insensitivity to reflected light (tolerating up to -16 dB or 2.5% optical feedback) eliminates the need for optical isolators, enabling efficient coupling with silicon-based waveguides. This facilitates high-density, low-power optical interconnections, thereby significantly enhancing communication efficiency within AI computing clusters and data centers. Meanwhile, the application of quantum dot single-photon sources in cutting-edge technologies such as quantum computing, quantum communication, and quantum sensing has positioned this field as a strategic focus in global technological competition. With the accelerated development of intelligent vehicles, temperature-insensitive QD lasers are also expected to become the light source of choice for in-vehicle optical fiber communication systems.

Ming Lu
（ Professor of Fudan University）
Abstract of Speech：In contemporary silicon photonics integration, III-V light sources are used. However, these light sources are incompatible with CMOS silicon processes, and the resulting hybrid silicon photonics integration keeps the light source packaging cost high.

This report presents our methods for improving silicon luminous efficiency, as well as the optically pumped all-silicon lasers developed on this basis. It will also report on the developed all-inorganic all-silicon LEDs, the improvement of their brightness and efficiency, and the prototypes of electrically pumped all-silicon lasers, among other achievements. Finally, it will provide an outlook on the realization of complete monolithic silicon photonics integration.
