Transmission and demodulation of multi-polarization-multiplexed signals

We propose the configuration of signal multi- plexing with four polarization states and investigate its transmission performance over single-mode fiber links. Using coherent detection and digital signal processing, a demodulation scheme for four-polarization-multiplexed （4PM） system is presented. We discuss the impact of crosstalk from polarization mode dispersion and polarization beam splitter misalignment on the proposed 4PM system. Furthermore, the transmission distance could be doubled to -50 km by employing feedback decision equalizers.

光栅单色仪和光电倍增管的偏振效应

本文对44W光栅单色仪及光电倍增管,在4200(?)—7400(?)波长范围内给出了偏振效应随波长的变化情况。结果表明:在所研究的光谱范围内,光栅的偏振效应特别显著,随波长变化很明显。而光电倍增管的偏振效应随波长变化比较缓慢,且绝对值也较小。因此,在光谱测量中,特别是在偏光测量中,光栅的偏振效应的影响是不能忽略的。     

Why did John Herschel fail to understand polarization? The differences between object and event concepts

This paper offers a solution to a problem in Herschel studies by drawing on the dynamic frame model for concept representation offered by cognitive psychology. Applying the frame model to represent the conceptual frameworks of the particle and wave theories, this paper shows that discontinuity between the particle and wave frameworks consists mainly in the transition from a particle notion ‘side’ to a wave notion ‘phase difference’. By illustrating intraconceptual relations within concepts, the frame representations reveal the ontological differences between these two concepts. ‘Side’ is an object concept built on spatial relations, but ‘phase difference’ is an event concept built on temporal relations. The conceptual analyses display a possible cognitive source of Herschel’s misconception of polarization. Limited by his experimental works and his philosophical beliefs, Herschel comprehended polarization solely in terms of spatial relations, which prevented him from replacing the object concept ‘side’ with the event concept ‘phase difference’, and eventually resulted in his failure to understand the wave account of polarization.
