论文摘要
我们在玻璃板上报告了一个缺口形的Coplanar微波波指导天线，该玻璃板设计用于在芯片上检测荧光纳米座（NDS）的光学检测到的磁共振（ODMR）。 Coplanar波导中Notch区域中心的一条图案图案的细线实现了一个毫米尺度的ODMR检测区（1.5 x 2.0 mm^2）和Gigahertz-Broadband Tructions（较低）（约8％）。检测区域中的ODMR信号强度可以通过数值模拟在定量上预测。使用此芯片设备，我们在细胞，组织和蠕虫的检测区域表现出均匀的ODMR信号强度。目前的基于芯片的微波体系结构的演示将使基于ODMR的量子传感技术可扩展的芯片集成到各种生物测定平台中。
We report a notch-shaped coplanar microwave waveguide antenna on a glass plate designed for on-chip detection of optically detected magnetic resonance (ODMR) of fluorescent nanodiamonds (NDs). A lithographically patterned thin wire at the center of the notch area in the coplanar waveguide realizes a millimeter-scale ODMR detection area (1.5 x 2.0 mm^2) and gigahertz-broadband characteristics with low reflection (about 8%). The ODMR signal intensity in the detection area is quantitatively predictable by numerical simulation. Using this chip device, we demonstrate a uniform ODMR signal intensity over the detection area for cells, tissue, and worms. The present demonstration of a chip-based microwave architecture will enable scalable chip integration of ODMR-based quantum sensing technology into various bioassay platforms.
