我们介绍了基于光纤的低温共焦显微镜的设计和操作。它被设计为一个紧凑的冷指，适合在超导磁体的孔内，这是一个模块化的单元，可以很容易地在稀释制冷机和其他低温恒温器之间交换使用。我们的目标是在量子光学实验中的应用与电子自旋在半导体和设计已被优化的驱动和检测光场具有明确的偏振。这是通过经由保偏光纤的光学接入以及冷指处的Voigt几何结构来实现的，该冷指避免了高磁场中光学部件中的法拉第旋转。我们的单位是多功能的实验中使用，测量光致发光，反射，或传输，因为我们证明了与施主束缚电子在薄GaAs薄膜的合奏量子光学实验。
We present the design and operation of a fiber-based cryogenic confocal microscope. It is designed as a compact cold-finger that fits inside the bore of a superconducting magnet, and which is a modular unit that can be easily swapped between use in a dilution refrigerator and other cryostats. We aimed at application in quantum optical experiments with electron spins in semiconductors and the design has been optimized for driving with and detection of optical fields with well-defined polarizations. This was implemented with optical access via a polarization maintaining fiber together with Voigt geometry at the cold finger, which circumvents Faraday rotations in the optical components in high magnetic fields. Our unit is versatile for use in experiments that measure photoluminescence, reflection, or transmission, as we demonstrate with a quantum optical experiment with an ensemble of donor-bound electrons in a thin GaAs film.
