摘要

光栅辅助反向定向耦合器（gacdc）是一种多功能光子器件，可以实现自由频谱范围的自由加降平顶响应，使其成为波分复用（WDM）系统和许多其他需要频谱整形的应用的有趣解决方案。它们的带宽可以通过热手段动态改变，在设计和应用中赋予额外的自由度。涉及光栅周期性（基音啁啾）的设计技术可以增强这种动态控制的效果，在保持控制机制和功率不变的情况下，在中心信道波长和通频带宽度方面都具有更宽的带宽可调性。在这项工作中，我们研究了这些影响的局限性，并通过模拟光学响应和热控制来突出其优势。

Enhanced Bandwidth Tunability in Thermally Controlled Multi-Pitch Contra-Directional Couplers

Grating-Assisted Contra Directional Couplers (GACDCs) are versatile photonic devices which can implement free-spectral-range free add-drop flat-top responses, making them interesting solutions for Wavelength Division Multiplexing (WDM) systems and many other applications requiring spectral shaping. Their bandwidth can be dynamically changed through thermal means, granting an additional degree of freedom in their design and application. Design techniques involving the periodicity of the gratings (pitch chirping) can enhance the effect of this dynamic control, leading to wider bandwidth tunability in terms of both central channel wavelength and passband width, while leaving the control mechanism and power unchanged. In this work, we investigate the limits of these effects, highlighting the advantages through simulation of both the optical response and the thermal control.
