Abstract

The intensity of light radiated from a fiber-optic light tap is observed to depend sensitively on the phase difference between LP01 and LP02 modes in a few-mode fiber. This observation is used to design a novel dual-mode interferometer in which light loss through the light tap is monitored, eliminating the need for a bulky spatial filter at the exit end of the fiber. Application of the device as an interferometric temperature sensor is described.
