摘要

连续介质中的束缚态(bic)由于其无限寿命与辐射损失的完全抑制有关，代表了共振光子学的新范式。这种特性使得用标准远场光谱技术直接测量bic也不可能。本文利用近场激发和检测显微镜直接观察了BIC的时间演化。

Direct Observation of THz Bound States in the Continuum

Bound states in the Continuum (BICs) represent a new paradigm for resonant photonics due to their infinite lifetime associated with the full suppression of radiation losses. This property makes it also impossible to directly measure BICs with standard far-field spectroscopic techniques. Here, we directly observe the temporal evolution of a BIC by using a near-field excitation and detection microscope.
