DESHIMA的集成滤波器组：基于超导谐振腔的亚毫米成像光谱仪
Integrated Filterbank for DESHIMA: A Submillimeter Imaging Spectrograph Based on Superconducting Resonators
摘要：
集成滤波器组（IFB）与微波动力学电感探测器（MKID）相结合，两者都基于超导谐振器，可用于制作紧凑灵活的宽带亚毫米成像光谱仪。为了研究DESHIMA（Delft SRON High-redshift Mapper）采用IFB结构的可能性，我们利用电磁场模拟研究了共面波导IFB的基本特性。我们表明，如果传输损耗可以忽略不计，可以实现大于1/2的耦合效率。我们得到了一个实际的设计，9像素× 920彩色三维成像设备，适合在4英寸的晶片，瞬时覆盖多个亚毫米大地窗口的f/df = 1000的色散。
英文摘要：
An integrated filterbank (IFB) in combination with microwave kinetic inductance detectors (MKIDs), both based on superconducting resonators, could be used to make broadband submillimeter imaging spectrographs that are compact and flexible. In order to investigate the possibility of adopting an IFB configuration for DESHIMA (Delft SRON High-redshift Mapper), we study the basic properties of a coplanar-waveguide-based IFB using electromagnetic simulation. We show that a coupling efficiency greater than 1/2 can be achieved if transmission losses are negligible. We arrive at a practical design for a 9 pixel x 920 color 3 dimensional imaging device that fits on a 4 inch wafer, which instantaneously covers multiple submillimeter telluric windows with a dispersion of f/df = 1000.
