研究了利用梯度折射率光纤准直器实现光纤与芯片光耦合的方法。利用光子集成电路技术制作的光栅耦合器和条形波导的实验表明，GRIN光纤准直器的峰值耦合效率比单模光纤低7.8dB。然而，3-dB对准容差提高了约5.7倍，从而产生了可插拔传感器解决方案。这项工作开辟了一条通往一个具有成本效益和便携式传感器平台的基础上，使用GRIN光纤准直器可插拔的光子生物传感器。(C)2021年，美国光电仪器工程师学会（SPIE）
Fiber-to-chip light coupling using a graded-index (GRIN) fiber collimator is investigated. Our experiments with grating couplers and strip waveguides fabricated in a photonic integrated circuit technology reveal that the peak coupling efficiency of a GRIN fiber collimator is 7.8 dB lower than that of a single-mode fiber. However, the 3-dB alignment tolerance is improved by a factor of about 5.7 giving rise to pluggable sensor solutions. This work opens a path toward a cost-effective and portable sensor platform based on pluggable photonic biosensors using GRIN fiber collimators.
