Adaptive Mode Control for Few-Mode Fiber Based Sensors and Sensor Networks

The development of mode division multiplexing has found numerous interesting applications in optical sensing. A major challenge has been how to control the mode composition of the interrogation signals. In this work, we presented a time-domain method that can adaptively control the form of optical signals at multiple locations in a two-mode-fiber. We also carry out a preliminary study that suggests the method of adaptive mode control is compatible with the requirements of optical sensing.
