摘要

连续介质中的准束缚态（q - bic）可以通过高q腔模式实现低阈值激光，但它们的极化可调性仍然受到纳米结构施加的腔对称性的限制。通过设计一个合适占空比（0.34）的微腔，通过开关泵极化，展示了一种偏振可切换分布反馈（DFB）激光器，其发射跃迁在双关闭Γ q - BIC激光和单Γ点布拉格共振（BR）激光之间可控。该开关机制在改变DFB结构的波导厚度和光子晶体周期时表现出前所未有的鲁棒性。这一发现将DFB激光器的能力扩展到传统极限之外，为纳米光子学、经典光学和量子光学应用开辟了机会。

Dynamically Switchable Polarization Lasing Between q‐BIC and Bragg Resonance Modes

Quasi‐bound states in the continuum (q‐BICs) enable low‐threshold lasing through high‐Q cavity modes, yet their polarization tunability remains constrained by nanostructure‐imposed cavity symmetries. By engineering a microcavity with a suitable duty cycle (0.34), a polarization‐switchable distributed feedback (DFB) laser is demonstrated with controlled emission transitions between dual off‐Γ q‐BIC lasing and single Γ‐point Bragg resonance (BR) lasing through switching pump polarization. The switching mechanism shows unprecedented robustness in varying waveguide thickness and photonic crystal period of DFB structures. The findings extend the capabilities of DFB lasers beyond their conventional limits, opening opportunities for nanophotonics, classical and quantum optics applications.
