The 2025 Photonics and Electromagnetics Research Symposium (PIERS 2025 in Chiba) was held from November 5 to 10, 2025, in Chiba, Japan. Professor Zhang Wei attended the conference and delivered an invited talk titled "Integration of InGaAs/InP Single Photon Avalanche Diodes on Quantum Photonic Chips" in the special session on "Quantum Information Processing and Devices." He provided a detailed introduction to the research team's recent advances in the hybrid integration of semiconductor avalanche diode single-photon detectors and quantum photonic chips, which attracted widespread attention from the attendees.

PIERS: PhotonIcs and Electromagnetics Research Symposium, also known as Progress In Electromagnetics Research Symposium, provides an international forum for reporting progress and recent advances in the modern development of electromagnetics, photonics and exciting applications. PIERS has become a major symposium in the area related to electromagnetics.
