太阳系尺度系外行星和原行星的高对比度成像需要仪器的进步，以在比当前技术更小的角间距下实现更深的星光抑制。光子灯笼（PL）的多模到单模转换能力因其单模波导固有的空间滤波特性，为实现零值干涉测量等技术提供了新途径。本文展示了基于全光纤焦平面零值干涉仪的实验室结果，该干涉仪使用工作在1550nm的现成组件。我们展示了用于将光耦合到仪器中的PL的实现，并将其与激光直接注入干涉仪的情况进行比较。PL与干涉仪的集成证明了它们为基于光子的科学仪器提供光源的潜力。此外，我们还讨论了扩展该仪器用于探测吸积原行星的概念。
英文摘要
High-contrast imaging of Solar System scale exoplanets and protoplanets demands advancements in instrumentation to access deeper starlight suppression at smaller angular separations than today's state-of-the-art. The multi-mode to single-mode conversion capabilities of photonic lanterns (PLs) provide new avenues to implement techniques such as nulling interferometry due to the inherent spatial filtering of single-mode waveguides. In this work, we present laboratory results on an all-fiber-based focal plane nulling interferometer using off-the-shelf components operating at 1550 nm. We demonstrate the implementation of a PL for coupling light into the instrument, and compare it to the case when laser light is directly fed into the interferometer. The integration of a PL with the interferometer evidences their potential for feeding photonic-based science instruments. Additionally, we discuss expanding the concept of the instrument for the detection of accreting protoplanets.
