Multiple-dimensional photonic measurements based on mapping technology

Optical communication technology has made great strides for several decades and various multiplexing technologies have been developed to greatly increase the communication capacity, such as time division multiplexing technology, wavelength division multiplexing technology, polarization division multiplexing (PDM) technology and mode division multiplexing technology (MDM), etc. The high-speed development of these multiplexing technologies motivate the demands for measurement of these optical parameters, such as mode, polarization and frequency. In this paper, we will review some research advances on the measured methods of mode distribution and polarization state of light in our group, including measurement of orbital angular momentum modes, linearly polarized modes and polarization modes. These works represent new progresses in spatial mode analysis and polarization analysis, showing great potential for applications in communication systems with MDM and PDM.
