摘要	A resonator sensing device having an optics coupler device (22) for communicating light between light sourcc(s) and scnsor(s) and a hollow core fiber resonator. Light from one resonator fiber tip is coupled to a second resonator fiber tip via a graded index (GRIN) lens (102, 104) having the appropriate pitch such that the maximum coupling efficiency is achieved and having two angled surfaces. The angled surfaces are coated with an appropriate coating having a reflectance R in order to achieve the desired degree of coupling. Light reflected by the second angled surface is captured with another lens (such as a microlens (32)) and coupled to a third fiber segment (coupled port). The optical parameters for the GRIN lens and the microlens are tailored to have the least loss.
其他摘要	一种谐振器传感装置，具有光学耦合器装置（22），用于在光源和传感器之间传递光和空心光纤谐振器。来自一个谐振器光纤尖端的光通过具有适当间距的渐变折射率（GRIN）透镜（102,104）耦合到第二谐振器光纤尖端，使得实现最大耦合效率并具有两个成角度的表面。倾斜表面涂覆有具有反射率R的适当涂层，以实现所需的耦合程度。由第二倾斜表面反射的光被另一个透镜（例如微透镜（32））捕获并耦合到第三光纤段（耦合端口）。 GRIN透镜和微透镜的光学参数经过定制，损耗最小。
