摘要
与干涉模式的不同相移相对应,基于耳语画廊模式谐振器的法诺共振呈现出各种独特的光谱线形,可应用于传感、光信号处理等领域。然而,大多数线形调谐方法都以改变传播相移或耦合强度为目标,普遍存在效率相对较低和调谐范围有限的问题。本文利用精心设计的波导锥耦合微环谐振器结构,并在光栅耦合器的辅助下,首次在频率和横向空间两个独立的调谐维度上展示了法诺共振的近乎全线形选择性,这意味着可以在整个 C 波段的特定共振波长上获得任意线形,包括洛伦兹倾角、非对称法诺峰或类似电磁诱导透明(EIT)的峰值。除了不同类型的线形外,还可以通过动态调整耦合位置来提高消光比。这项研究为操纵法诺共振的透射光谱提供了一种有效的方法,对促进其在集成光子学平台上的进一步应用具有重要意义。
Frequency‐Space Selective Fano Resonance Based on a Micro‐Ring Resonator on Lithium Niobate on Insulator
Corresponding to the different phase‐shifts of the interference modes, the whispering gallery mode resonator‐based Fano resonance exhibits a variety of unique spectral lineshapes that can be applied to sensing, optical signal processing, and so on. However, most approaches to lineshape tuning aim to alter the propagation phase‐shift or coupling strength, and generally suffer from relatively low efficiency and limited tuning range. In this paper, with a carefully designed waveguide‐taper coupled micro‐ring resonator structure and the assistance with the grating‐coupler, for the first time a near full‐lineshape selectivity of the Fano resonance is demonstrated in two isolated tuning dimensions of the frequency and transverse space, which means arbitrary lineshapes including the Lorentzian‐dip, asymmetric Fano peak or electromagnetically‐induced‐transparency (EIT)‐like peak can be obtained at a specific resonance wavelength in the whole C‐band. In addition to the different types of line shapes, the extinction ratio can also be enhanced by dynamically tuning the coupling position. This research provides an efficient approach to manipulate the transmission spectra of the Fano resonance, which is of great importance in promoting its further applications on integrated photonics platforms.
