A conventional Michelson interferometer is modified and used to form the various types of interferometers. The basic system consists of a conventional Michelson interferometer with silicon-graphene-gold embedded between layers on the ports. When light from the monochromatic source is input into the system via the input port (silicon waveguide), the change in optical path difference (OPD) of light traveling in the stacked layers introduces the change in the optical phase, which affects to the electron mean free path within the gold layer, induces the change in the overall electron mobility can be seen by the interferometer output visibility. Further plasmonic waves are introduced on the graphene thin film and the electron mobility occurred within the gold layer, in which the light-electron energy conversion in terms of the electron mobility can be observed, the gold layer length is 100 nm. The measurement resolution in terms of the OPD of 50 nm is achieved. In applications, the outputs of the drop port device of the modified Michelson interferometer can be arranged by the different detectors, where the polarized light outputs, the photon outputs, the electron spin outputs can be obtained by the interference fringe visibility, mobility visibility and the spin up-down splitting output energies. The modified Michelson interferometer theory and the detection schemes are given in details.
对传统的迈克尔逊干涉仪进行了改进，并用于构成各种类型的干涉仪。基本系统由一个传统的迈克尔逊干涉仪组成，在端口的各层之间嵌入了硅-石墨烯-金。当来自单色光源的光通过输入端口（硅波导）输入到系统中时，在堆叠层中传播的光的光程差（OPD）的变化会引入光相位的变化，这会影响金层内的电子平均自由程，导致整体电子迁移率的变化，可通过干涉仪输出可见度观察到。进一步在石墨烯薄膜上引入等离子体波，并在金层内发生电子迁移率变化，其中可以观察到基于电子迁移率的光-电子能量转换，金层长度为100nm。实现了50nm的光程差测量分辨率。在应用中，改进后的迈克尔逊干涉仪的下端口器件的输出可以由不同的探测器进行排列，通过干涉条纹可见度、迁移率可见度和自旋上下分裂输出能量可以获得偏振光输出、光子输出、电子自旋输出。详细给出了改进后的迈克尔逊干涉仪理论和检测方案。
