Abstract:
The CLEO EUROPE-EQEC conference was held in Munich, Germany, on June 23, 2025. Doctoral student Xujia Zhang from the research group attended the conference and engaged in on-site academic exchanges.
CLEO EUROPE-EQEC stands as one of the most influential conference series in Europe within the fields of optics, photonics, and quantum technologies. This event brought together researchers from scientific institutions, universities, and enterprises worldwide, focusing on multiple cutting-edge research areas such as laser physics, ultrafast optics, nonlinear optics, quantum photonics, integrated photonic chips and devices. A wide range of achievements representing the highest level of current academic research were presented. The conference took place from June 23 to June 27, 2025, in Munich, Germany. Doctoral student Xujia Zhang attended and delivered an oral presentation, engaging in in-depth discussions and exchanges with international peers in the field.

During the conference, Xujia Zhang, as the first author, delivered an oral presentation titled "Broadband Mode-Locked III-V/LiNbO₃ Microcomb Laser." This work demonstrated the generation of a broadband mode-locked microcomb through heterogeneous integration of a broadband gain RSOA and a thin-film lithium niobate phase modulator.

In addition to his presentation, Xujia Zhang actively attended multiple sessions on related topics, with particular focus on recent advances in integrated mode-locked lasers, electro-optic modulators, nonlinear optical devices, as well as platforms based on thin-film lithium niobate and lithium tantalate. He paid special attention to several presentations by members of Prof. Tobias J. Kippenberg's group at École Polytechnique Fédérale de Lausanne (EPFL), which covered erbium-doped single-frequency tunable lasers on silicon nitride platforms, Mamyshev mode-locked lasers, and on-chip frequency comb research. Furthermore, Xujia Zhang followed numerous studies on devices and applications developed on thin-film lithium niobate and lithium tantalate platforms, including arrayed waveguide gratings, Bragg gratings, mode converters, integrated frequency comb systems, and microwave generation. These sessions significantly broadened his understanding of integrated photonic material platforms and provided valuable inspiration for his future research directions and topics.
